I have a major problem going on here. I have been using Premiere 6.5 over a period of months to make my movie. The timeline had title files, tif files, avi files and a few transitions. The last thing I did was add a tif file in the alpha channel so background strips showed and added another video track to take a 3D effect, plus an mp3. Some time after doing this (and I don't know if something about this was responsible) I noticed there were no coloured lines above the avi files to tell me if they had been rendered or not. When I tried rendering them nothing happened. This seems to have ruined the entire software in that I am no longer able to render avi files!
I uninstalled and reinstalled Premiere 6.5 and during setup it told me "Unable to launch Adobe_1\TCW\tcwi.exe". Premiere will render any file but avi files which makes it useless. I even imported a brand new avi file in case the others I used to make my movie had become corrupted. It would not render.
What on earth can I do? Help will be much appreciate. I have lost many, many hours of work.
