I've finally upgraded to a new MBP and now running mountain lion. I knew there was going to be an issue with some of my QC files, and I'm going through them one by one, some don't work at all, some seem to work in QC itself, but not in ME. If anyone has dealt with this, are there any problem patches I should pay attention to? I have to break each composition down to debug the problems in ME, and still not at all sure why some of my comps just won't work in ME.
