I couldn’t find FCPrescue on version tracker, but via Google, found a version of it that said it worked with FCP version 5, and hoped this was the same software you recommended.
I downloaded and unzipped it. It had 2 choices – trash and backup (with no explanation of what these choices did on the menu or with the software). I pressed trash, I figured at the worst it would dump my trash for me.
Now my FCP opens. My assumption is it trashed my preferences. Either way it worked and I thank you. I am pretty adept in using software but have little background or knowledge in fixing it. So your well thought out advice is very very appreciated.
And for anyone reading this who has not used FCPrescue, it claims to be a handy tool for erasing preferences set up by someone who borrow your system.
Thanks Steve and happy 4th! Cindy
