I have similiar problem, PD8 crashes whenever I try to use Titles (create or edit a Title) or try to Produce a video, and on many other things.
I was able to creat a project (without any titles) without the program crashing, burt I can't get beyond that.
The email support has been worthless since I have not received a reply to my two messages about PD8 crashinig all the time. I reinstalled it but it made no difference.
I was hoping to see some response from a technical support person in this forum, but where are they?
I have Win 7 Ultimate 64, and a Intel Core 2 Quad 2.66GHz 8GB mem, ATI Radeon HD4650 and Blu-Ray RW
