I can't get my project to render. It was working ok last night. then i went to work on it this morning and it shows the clip, complete with the picture in the clips, but the preview screen is black. when played in the trimmer the clips work. it's only from the main timeline that they don't.
Sound doesn't work from the main timeline either.
I have vegas 9.0 platinum. I don't know what's going wrong. thanks!
