Hey guys ok i got two differnt cd keys with my game one in the case and one on the back of the manual.....I am trying to play multiplayer on ubi but it ask me for a cd key.... i have tryed both of them and one wont fit and the other one will but it says there is an error.... if anyone might know what the problem is could u please let me know.... & i look forward to playing with you guys soon!!!!!!!

I have the same problem.... please if someone have found the fix please write.. thanks

The CD key inside the case is for installation. The key printed on the back of the manual is, I assume, for multi-player.

Make sure you enter the correct characters (e.g. because of the fonts they use for the codes, a B can be mistaken for an 8, a 0 (zero) can be mistaken for an O, etc.).
