Had same issue after newest update.  I installed new drivers for my GPU, and reinstalled MW2, fixed it.

My game crashed and I started a scan and repair then kept getting and error around 70% I also tried reinstalling and got the same error. I then restarted my PC and tried to scan and repair again and it is just stuck in a loop now. Any ideas?
