Well, I can only play the mod for about 5 minutes before my screen starts glitching out/artifacting to the point where I cant see, then my game crashes with a .NET Framework error message. (This also crashes every other program on my PC that uses .net). After this my ArmA won't even start because the .exe crashes as soon as it loads. Here is an error I'm getting in event viewer: Log Name: Application Source: Application Error Date: 5/5/2012 4:28:04 PM Event ID: 1000 Task Category: (100) Level: Error Keywords: Classic User: N/A Computer: Jack-PC Description: Faulting application name: arma2oa.exe, version: 1.60.87.580, time stamp: 0x4ef2c80b Faulting module name: atiumdag.dll, version: 7.14.10.903, time stamp: 0x4f7e480d Exception code: 0xc0000005 Fault offset: 0x003470c0 Faulting process id: 0xfc0 Faulting application start time: 0x01cd2afd89cc2ba0 Faulting application path: C:\Program Files (x86)\Steam\steamapps\common\arma 2\arma2oa.exe Faulting module path: C:\Windows\system32\atiumdag.dll Report Id: d0c6abc0-96f0-11e1-a791-6c626db3033f Event Xml: 1000 2 100 0x80000000000000 19346 Application Jack-PC arma2oa.exe 1.60.87.580 4ef2c80b atiumdag.dll 7.14.10.903 4f7e480d c0000005 003470c0 fc0 01cd2afd89cc2ba0 C:\Program Files (x86)\Steam\steamapps\common\arma 2\arma2oa.exe C:\Windows\system32\atiumdag.dll d0c6abc0-96f0-11e1-a791-6c626db3033f It seems that the problem is this atiumdag.dll. I googled it and got nowhere. I reinstalled my Graphic drivers and .net, still nothing. Does anyone have any clue what is wrong?
