As far as I know, you should be able to activate it without any problems mate.

It depends on how many times you have activated it, I think there is a limit of around 20, you will get a message stating that the registration has bee acceded when you reach the limit, then all you have to do is call MS and notify them why you have acceded the limit, they will then reset your account.
