If you registered it then THQ might be able to help you out - go to their tech support and see (no guaruntees though).

Blah. I cant even play online because my cd key is... um.. "invalid".

Whatever. Thats what a LAN is for.

Kruniac: If you get the CD key is invalid message you probably entered it incorrectly. There's a thread on how to fix that in the MTL.
