Red thumbnails?
 

I have this issue, I have a file that has many edits, all done on the dv proxies using gearshift, all the mt2 files are there and working just fine if played individually, but when I switch to them they don't all load, they all say switched but only a few are there the rest are just red, and wont play or do anything, then crashes? Any clues?

I have also tried in Vegas 8 as well, same issue, I have both versions if that helps, it was all done in 7 and I would prefer to finish in 7 but can switch if needed I did upgrade to 8.

Thanks.
