I bought this game today and put in a wrong disk while installing and now it get a "catastrophic failure" everytime i try to install it. I restarted my computer and tried to uninstall by going to add/remove programs but i got the same error.

I also tried installing it on another computer than copying the directory to my computer but when i try to play online it says "wrong version" even though it works fine on the computer i installed it on.

please someone help, i cant find a solution to this anywhere
