I am trying to nstall final cut express on my powerbook. The box says upgrade on the front lower-left hand corner. when i type in the serial number in the install. a second screen pops up asking for another serial number. I only have one and it won't take the serial number a second time and therefore won't let me install? What should I do?
I also have never owned another version of final cut express. This is the only one i have owned, and I was told the upgrade doesn't mean anything
