FCE Serial Number
After using Final Cut Express for many years and upgrading when this was available I now find that I cannot access the application. Today I went to use the application and it requested that I enter the Serial Number before proceeding. This I did only to find that this was not accepted and I could not proceed to use FCE. I have used it constantly since it was available but not during the past 4 months. Does Mountain Lion make a difference although I would have thought that this in use last November. Any clues to overcoming my problem as I would like to again us it.
OS X Mountain Lion (10.8.3), MacPro Computer
