I was editing yesterday and everything was working like normal. I am using Vegas 9. I was adjusting the contrast on some of my clips, then I went to multicam edit, now since then all of the clips have been reset and i can't use any of the plug-ins on any of the clips. I can open them up but when I adjust anything it doesn't do anything. Am I missing something or what? Any help would be appreciated!

Sounds like you pressed the "Split Screen" button above the preview screen...
