I posted earlier about Vegas 6d showing some clips offline and showing those as RED instead of the usual BLACK. This happened after installing v3.03 over v3.01. Presumably nobody else has been hit by this or you would have mentioned it. I've done the complete uninstall, even under Cineform Support guidance, but still the same. Fortunately restoring the machines back to an earlier date (i.e. to v3.01) gets me going again. CF Support is still investigating, but any experience (even "no problem") might offer guidance.
Odd thing is that not all clips are affected.
