I can't get Final Cut Pro to work
Final Cut Pro says I need to buy it again. I got it many years ago when I bought my first Mac at Best Buy. They installed the software for me and gave me the disk. I have moved twice and I have upgraded my Mac twice. To get Final Cut on any new computers I transfered data to a new Mac. I don't have my disk anymore or any paperwork. I don't know what information they use to install it because they didn't have an App store account set up for me. It's not software I use that often but I paid a lot of money for it and I would like to have it operational. How can I get it up and running.
