Hi,
In case anyone’s still watching this thread; I managed to get my FCP started again with the help of Eric’s response:
I went to ~/Library/Application Support/Final Cut Studio/Motion/Templates
and deleted everything in there. So now FCP starts. At some point I’ll do a complete reinstall but that’ll get me through for now.
My guess is that if anyone’s reinstalling FCP 7 and not having any luck then they should double check this folder is ditched before reinstalling as it might be stubbornly hanging around….
