Thanks for the help.I uninstalled everything but I can't re-install because I don't have the disc's or code's here with me(didn't think it through).I can re-install PZr Corp Soviet but that's the only one right now.

I have been playing Panzer corps with no problem it's only since I installed the new soviet corps.I already uninstalled and then installed it again,but the same thing keeps happening.

I keep getting CRC check failed when I hit play.Anyone have an answer?
