I have been doing video editing for a non-profit (my church). At the time I started, they already had purchased Final Cut Pro and gave me their AppleID login information so I could install it on my personal Mac for the purpose of editing their videos. I have since purchased my own copy of FCPx, but when I was notified of an update on the above mentioned Mac, it prompted me for the church AppleId in order to update the software. How can I change the AppleId associated with Final Cut Pro? I hope I don't have to delete it from my Mac and reinstall, as I've added a number of customizations and add-on titles, transitions, lower thirds, etc.
