Just had AE installed and I can't import any video (.avi or .mov.) They show up grey and then if I try all files it says "it's a bad format or not readable." Two error messages about unknown exception and missing output plug-in show up when I opne AE. I have AE CS5.5, 10.6.8 Mac, QT 10 in applications file and QT 7.6.6 in utilities just installed today. I tried throwing out preferences but nothing seems to help. Plaese help me.
