Okay - E-on came through with the fix and everything's working fine now. For anyone with a Mac that ever has this problem: Go to the "Library Folder" on your Mac's Hard Drive, open it and look for the "Application Support" folder, open that and find the file "Vue5Trial.reg" and delete it. Then try running the program again. Make sure there are no hidden spaces before or after the reg number when you enter it. That's ALL there was to it! AMAZING!
