Critical error when starting up??

Build KillingFloor_Build_[2009-02-09_10.82]

OS: Windows XP 5.1 (Build: 2600)
CPU: GenuineIntel PentiumPro-class processor @ 2136 MHz with 2046MB RAM
Video: No Video

Can't find 'ini:Engine.Engine.GameEngine' in configuration file

History: UObject::SafeLoadError <- UObject::StaticLoadClass <- InitEngine <- FMallocWindows::Free <- FMallocWindows::Free

This message pops up when I start the game. I played for two hours yesterday, then I tried to play today and this came up. Tried to submit a ticket but it says the web page doesn't exist. Can someone help?

try deleting your killingfloor.ini in the kf system folder and trying to play again.
