I've researched this problem extensively online and via the Adobe forums. The problem seems to have a multitude of causes and solutions, none of which worked for me. The only thing I haven't tried is a complete reformat and reinstallation of my OS which seems a rediculously drastic solution for what seems like a bug with either PP CS6 or Win8.
Also, as far as I can tell, I haven't made any other changes to Premiere whatsoever since the upgrade.
Thanks in advance for any help you can offer.
Have you tried reinstalling PP?
Yes, I've tried re-installing twice, but to no effect. I've tried every solution I could find online (and there were many) short of reformatting and reinstalling my OS, and nothing has worked.
Well, it may be time for a reformat. CS6 does work just fine on Win 8, so something somewhere got messed up.
