I am regularly getting import errors 81 and 39 as well as abort errors when trying to work on my project. It seems the media won't render. It always happens late Friday nights when I'm on deadline, but the software works fine every other day of the week. I can't find useful help online to troubleshoot, and there's not a diagnostic panel or way to resolve the issues within Premiere. I've tried restarting Premiere, restarting my computer, praying fiercely (this one is the only one that's really worked).
