^I know that very well thank you very much.The basic point is cracking of Star Force or for that matter any other protection methods isnt a topic to be discussing out here.Which is why I told this guy well in advance to refrain from asking for gathering a Cd key info.If you have the legit Copy and get this error(Which is very rare chance)then He could have promptly mailed the problem to Ubisoft's website.Since its an obvious case of Piracy and the Cd key invalid message stating that the key had already been blacklisted.there's no point in arguing over ways to acquire a Cd key.
