Far Cry 2 multiplayer?

Guys I bought Farcry 2 a couple of days ago and i just can’t manage to get to the online multiplayer part of the game!
I clicked on the button and created my account with UBI and now when i try to play the multiplayer game it is asking for my username and password (which I am entering in correctly) and then it is asking for an “online key” ! wtf is this “online key” and just how am i supposed to obtain it?? It does not allow me to type in numbers (only letters) so it can’t be my CD-Key, I am totally confused!
thanks guys
Answer #1
I think you have to register your game on the website of Ubisoft to obtain an online key for it.

Thanks for trying to help matey, you have been a member for a long time and not made many posts, one of the few posts you have made was trying to help someone in need.
As for my problem.. numbers can not be entered whilst capps lock is on, very simple and stupid bug that they must have missed
Thanks
