RF15-131 Client crashes in 49 seconds
When running the client, it will randomly crash within 49 seconds, and the longest time is 49 seconds. I will upload the server log below.

Reported: The client closes by itself within about a minute of starting, on the character screen or in the world.
Found: Both crashes in the server log happen exactly 61 seconds after the client first connects, whatever it was doing at the time, and the server records no error before the client drops. That points at something inside the client on a timer rather than at anything the server sent, and we cannot tell which part from the server log alone.
Needed:
- The crash dump the client writes each time it closes. It is a file called
crashdump.dmpin a folder under%LOCALAPPDATA%\CrashRpt\UnsentCrashReports\(paste that path into the Windows Explorer address bar). Please upload it to our Discord and tag Ron so he can collect it there. - The game version your server shows, and where your client files came from.
Okay, I will extract the crash log and send it to DC
Found: The crash dump shows the client closing inside AhnLab HackShield's startup, about a minute after launch, because it could not load the HackShield file ehsvc.dll. The client has to load that file even with HackShield disabled, so it cannot be deleted. The client patcher is what turns HackShield off, and the dump shows it had not been applied.
Step 1: put HackShield back. If you deleted anything from the client's HackShield folder, restore it from your original GamesCampus 1.5b download. The file HackShield\en-gb\ehsvc.dll must exist.
Step 2: check the client file. Open PowerShell and run this, replacing D:\RF15 with your client folder:
Get-FileHash "D:\RF15\RF_Online.bin" -Algorithm SHA1
9E673EBE8A78210A850A02C2C5B6BE7F7A253FEAis the unmodified GamesCampus 1.5b client. Go to step 3.
CE3FCF163A042ADE290485885238565A6693C46Cmeans it is already patched correctly. Skip to step 4.
- Any other value is a different client, and the patcher will refuse it. Reinstall the GamesCampus 1.5b client and start again.
Step 3: patch it. The patcher is tools\clientpatcher.ps1 in the server download. Run this as one line, replacing E:\rf15-v0.2.2 with your server folder and D:\RF15 with your client folder:
powershell -ExecutionPolicy Bypass -File "E:\rf15-v0.2.2\tools\clientpatcher.ps1" "D:\RF15\RF_Online.bin" -HackShield 0 -HsDialog 0 -Movie 0
The -ExecutionPolicy Bypass part is needed on Windows 11, which otherwise refuses to run downloaded scripts. The output should end with:
hackshield : ON -> OFF (4 site(s) written) hsdialog : ON -> OFF (1 site(s) written) movie : ON -> OFF (1 site(s) written) Wrote 3 patch(es) to D:\RF15\RF_Online.bin New sha1: CE3FCF163A042ADE290485885238565A6693C46C
A backup of the original file is saved next to it before anything is written.
Step 4: confirm and play. Run the same command without the last three options. It should say This client is already set up for a private server (the recommended patches are all applied). Then start the game through rflauncher.exe as before. An AhnLab logo appears for a few seconds on launch, which is expected; there should be no "HS Err 8" message box and no intro movies.
Needed: If it still crashes or the patcher shows anything different from the above:
- The full text of the PowerShell window (copy and paste, or a screenshot).
- The new
crashdump.dmpfrom%LOCALAPPDATA%\CrashRpt\UnsentCrashReports\.
- The file
NetLog\rfclient.logfrom the client folder.
Upload them to our Discord and tag Ron.
I always play hs err7 here instead of the hs err8 mentioned above
Reported: The client closes by itself about a minute after starting, with an "HS Update Err 7" box, on two different computers, even after the client patcher reported HackShield as already off.
Found: The patcher turned off HackShield's checks but left HackShield's updater running. The updater tries to reach an AhnLab server that no longer exists and waits up to 60 seconds for it. On our test machine it gives up at once and shows nothing; on your network it waits and then shows "HS Update Err 7". The client ignores the updater's result either way, so nothing is lost by not running it. That 60-second wait lines up with how long the client lasts for you, but we could not reproduce the crash itself, so whether this is the whole cause is not yet confirmed.
Fix: The client patcher now skips the HackShield updater as part of -HackShield 0, and a client patched with it boots and plays normally on our test machine. A client patched by the old patcher shows HackShield as MIXED and needs the same command run once more. This ships in the next rf15 update; Ron has already posted the
new patcher on Discord so you can test it now.
To verify: Save the patcher from that Discord message over tools\clientpatcher.ps1 in your server folder, then run the same command as before:
powershell -ExecutionPolicy Bypass -File "E:\rf15-v0.2.2\tools\clientpatcher.ps1" "D:\RF15\RF_Online.bin" -HackShield 0 -HsDialog 0 -Movie 0
- It should print
hackshield : MIXED -> OFF (1 site(s) written)andNew sha1: 276E33846C642F32301435B7C64E51111AA04EBA.
- Start the game through
rflauncher.exe. There should be no "HS Update Err 7" box, and the client should stay running past the first two minutes, on the character screen and in the world.
- If it still closes, upload the new
