Just be glad you guys can still at least play.
I’ve had to completely rebuild my machine due to issues with Avast vs. Punkbuster (in conjunction with Rainbow 6 Vegas 2 though). Totally corrupted my registry.
Yes, I’ve successfully recreated the error (by using System Restore points to go back to pre-install of Avast). It is clearly an Avast vs. Punkbuster issue.
Used Avast for quite some time now but looks like I will have to find something else.
