This worked for me. I was dealing with a project of HD footage from my camcorder, and for some reason Vegas was crashing every time I tried to edit the timeline in any way. It had worked fine up until today, but when I went back to the project, it crashed anytime I tried to delete a clip from the timeline, or even if I just left the program open for any extended period of time (more than a minute).
I thought maybe it had to do with some codecs I installed, so I uninstalled them to no effect.
I started a new project with the same template and settings, copied everything from the timeline in the original project, and pasted it into the new one, and this new project works fine.
*whew* I really didn’t want to have to reinstall Vegas today.
