Update on 9.0.8 locking up while opening: I found I had a few corrupted video clips in an event. Apparently from sudden quits during importing from a VHS/VCR. The corrupted clips had a generic thumbnail pic. Something to watch out for if you get a quit during importing.
I wound up trashing 9.0.8 and reinstalling 9.0 from the disc.
If you are looking for updates beyond 9.0 try this.
Your other post said you were looking for updates other than 9.0.8
Suggest you go to 9.0.4 if Mac OSX( 10.7.5) allows it.Not sure.
