Thank you, Saby - this worked for my problem, too. I am using PS21U, and when exporting a blu-ray, it would make the ''assets'' and then gt stuck at 50% completion - even left it overnight and it stayed at 50%. Then I renamed the AppData folder like you said, and it completed in ~2 hours.

Thanks for the reply!

I'm still using PS21U, and I'm having trouble with the menus -- there are a couple posts in this forum about bugs in the older version. Does PS24U work reliably? For example, my current project I exported as blu-ray and DVD; the blu-ray plays the intro clip and then goes straight into the main content, skipping the menu (which I can't access at ...

Are any of the newer versions of Studio any better at creating blu-ray disc images?  I don't have CUDA in my video card, but I'm still having issues in PS21Ultimate. If I make a blu-ray image, the menus and chapters are missing (player shows the intro video and jumps to the first chapter); if I make a DVD image (from the same project), it ...

Oh, hooray! I can edit in PS14 again! Thank you, saby! I had a little trouble, though. First, I uninstalled PS20 (which I had installed in my random attempts to get something to work). Then I tried to uninstall PS14, but I got an error: Another version of this product is already installed. Installation of this version cannot continue. To ...

Thanks. I have to boot up the old computer and let the uninstaller run first. I'll post back later.

I'm having a little trouble finding Regdelete. First did a google search, but then searched this forum, and found a number of broken links. I finally found https://support.corel.com/hc/en-us/articles/216091168-1722-error-on-install-of-Studio- which is for PS21. Will that work, or do I need a Regdelete specific to PS14?

So, Saby's suspicion was correct: he got me the new activation keys, but that wasn't the problem. The keys were accepted (I got dialog boxes about features being unlocked), but the player window still doesn't play. I suspect my registry may be damaged from installing/uninstalling/repairing PS14, 20, and 21 to try to resolve this. One further ...

It won't play .mpg files (like the Our Nature Adventure sample) nor the .avi files I imported from my DV camcorder. But I can see thumbnails of all the scenes in these files.

Saby, do you have another suggestion, if it's not missing keys? Thanks.
