I moved the hard drive containing Logic 9 to another computer, and when I tried to launch Logic, a window opened that asked for my name and the Logic 9 serial number. When I entered it, it said the number was not recognized. I tried three times, copying it very carefully from the sticker on the original paperwork, but it wouldn't work. I've migrated this drive before and didn't have this problem. Anyone know how to proceed? In case it matters, it's a sideways move from one computer to another of the exact same model-as it was last time also.
