Mp problems

[Firestorm]

Hej comrades !
i've a question about cd-keys
A friend of me asked me to borrow my wolf discs, he installed wolf.. with the correct cd-key, But the problem is that he can't play WOLF mp.. We already looked at the settings, but he still says theres an invalid cd-key..

So if anyone knows what to do about it, v44

your not allowed to play with the same cd key as him. altough my first wolf cd was shared with my friend. and we had a way of connecting to a server. just but a new cd key or ask somebody for one
