Duplicate GUID/CDKEY

I have no real idea, but does that mean you put the game on more than one computer?

Or someone else's key generator picked your CD key...

I haven't played on another PC.

But what can they do apart from playing on my
account? They cant block me, can they?

This definitely sounds like something you should take to Ubisoft support.

Double check the number when you put it in. Someone else may have activated your copy or what you put in doesn't match the package. It happens all the time when people are activating cell phones.

Keep your receipt!!! They are going to want proof of purchase.
