Why am I receiving an invalid registration key message?
This message is being displayed because a Pointstone product on your computer has recognized an invalid registration key. A registration key is invalid if it was illegally created, stolen or distributed over the Internet.
The TuneUp product installed on your computer is now locked and cannot be used again until an original registration key has been entered.
