The game wont let me play on ubi.com cause it says i need a online key.

i am having the same problem .. are we totally blonde or is there a secret we have not been told? If it's a secret then can someone please let us know

If you purchased it online and downloaded it; you should have an email with the code. If you have the physical game with the manual; it will be somewhere on the manual, most likely on the back and it will be called "CD-Key". You have to enter it exactly as it is shown ie; capital letters and dashes.

Be sure you type the right letter or number "O" and "0" can be confusing (ie the letter or the number).
