Running two video cards at once can lead to problems.
But, meantime, have you manually gone to Windows Update and ensured you have all of the non-critical updates (which don't download automatically, but can include important updates)?
Have you ensured you have the latest version of Quicktime, per the program's requirements?
Have you manually gone to the nVidia site and downloaded the latest version of your video card's driver? (Here's where you're going to run into problems, since you're trying to update the drivers for two different cards at the same time.)
Thanks for the reply.
I have my two graphics cards SLI sttings properly configured, and they have been working correctly for every other Premiere unctionality, as well as all of the rest of CS6 applications (and Lightroom). I have double-checked that I do have the latest drivers from nVidia's site.
I do have the latest QuickTime software.
I have gone in and updated all of the optional Windows updates.
I keep getting the same error, but I think I can describe it better.
When I go into the Movie Menu panel, the "Add a theme" link in the panel does not respond. When I click the Menu Theme button in the upper right corner of the Movie Menu panel, I do get the library of themes to select from, but when I select one, it does not load in to the panel. (It does download the content from online, though it doesn't show on the screen. I just see the "Add a theme" link in the middle of the page.) The Adjustments panel on the right is completely blank.
I can click the "Done" button to close the Movie Menu panel. But when I try to open the Movie Menu panel a second time, it crashes immediately and I get the error message from my last post in this thread.
I have repeatedly re-booted my computer, but I get the identical behavior. All of the other functionality of Premiere Elements still work.
If the next receommendation is to re-install the software, do I have to move my projects anywhere? Or do I just leave them and re-install?
Though for PrPro, here is a thread, where the OP was also on Win7, but running a BlackMagic card, and having the C++ Runtime Error. Might be some useful info in it: http://forums.adobe.com/message/2926924
