I'm currently using the Pro14 Trial. I'm editing an .AVI HD file. I get everything done the way I like it and when I go to export file it says "mixing down" and never completes, the software then locks up. I can do anything? Any ideas? It does create a file, but it has NOTHING on it. 0mb. I can't seem to mix anythign down an any type of format without it crashing. At this point, I'm happy with the software and would like to purchase, but don't want to have this problem ALL THE DANG TIME!
