Page 1 of Powerdvd on my pc having problems..........help needed

I was viewing a dvd & tried to use the "go to" feature, which worked ok for tracks 1-8, but then when I opted to go to track 9,the last track,it stops playing & I got the following message:-
Powerdvd has caused an error in DVD_X.IMP
If you continue to experience problems try restarting your computer.

Despite several restarts, I keep getting this message. Can anyone tell me what I need to do to make it work properly & stop the message from re-appearing?
