Pinnacle Studio 8 Crashing

Not sure if many people can help me here, but it’s worth a shot. I have Pinnacle Syduio 8 and it keeps crashing when I try to load a 45 minute file I was editing. Is there a reason why? My computer is a 1.6ghz Sony Vaio with 512megs of RAM and an 80gig HD.

I meant “Studio”.

Anyone?
