If the back-up was created after the file was opened, it won't work. To correctly make a back-up the file should first be saved to disc. The unopened file can then be backed up. If this was done correctly, or if you're working off an MTU supplied product cd, it would appear the serial number is not being input properly. Remember the email addres and serial number are case sensitive and must be entered exactly as shown in your instructions. If not input properly, the program simply aborts, just as you described.
Hope this helps
