X6 illegal copy

I have a disk and I and all of a sudden, I am getting an illegal copy message?!?  I am confused?!?  When I get into my Corel.com account, I have X6 registered.  I tried to uninstall and re-install but then it tells me that the key is already registered.  What is happening?!?!?  The chat guy disconnected me in the middle of my chat, and no one answers the phone?
