I might be going crazy but since I purchased Parallels in January of 07 I swear at some point in time I had to upgrade to PD 3.0 for $39.99 and when I upgraded they sent me a new registration number from the one that came with the book/disc or maybe I am dreaming? Does Parallels or the OS Is there somewhere I can look? Is there a way to validate that the one I have is the right one. I ask because I am having a larger Hard disk installed and they told me sometimes Parallels doesn't liked being just copied it wants to be reinstalled and if that's the case I hate to get stuck without the proper registration number.
