I did not notice if you tried to Import into a PrPro CS4 Project, or if you just tried to Open your Project. If you have not tried Import, that would be my next step. If you did, and that failed too, sorry.
Yes, it is on the list of many things I've tried.
Well, I was hoping for you. Sorry that I missed that above.
One question: are external HDD's in the equation anywhere? What about capture cards, like Matrox, BlackMagic, etc.?
No, all internal HDDs.
Files are taken from a camera that records to files so no capture cards either.
File fails the same way on multiple machines that do not have the assets.
Just odd to me because After Effects reads and loads it, so the data IS there.
