I have played MW2 a lot and have solved lots of issues with it over the years. I got a new computer and installed mw2 on it. The game loads fine but crashes under a range of circumstances (end turn, clicking a box away, for no apparent reason at all). I have tried tons of fixes already and still have the issue. Here are some of what I've tried: Installing steam (and mw2) on a new partition of the drive, verifying the integrity of the files, turning off antivirus (I've turned off basically all built in windows security measures), turning off UAC, running in compatibility mode, and probably more i've forgotten about. My main hypothesis is that it had to do with the .NET framework update, as it tried to install when I first ran the game but failed. However I have since then I had the windows updater run and installed all possible updates. But the crashes are so wideranging I feel like it must be something very core to how the game runs. The log file says lots of files are missing. Also with every crash my preferences seem to be reset. If anyone has knowledge of how to fix this issue it would be greatly appreciated. Thanks!
