The fix to install update for me was to delete the original then buy again (free of course).
However I started my first class teaching FCPX tonight and found my Events and Projects not working at local college due to older FPCX version.
No biggie just rebuild it during class time.
I did also notice that to use XML export you need to select the project from list.
Dumb was trying to export from timeline…and I call myself a teacher 😛
