I'm back. Same problem. Back in October it started working again with no reason why.
I am once again missing a project timeline because of this mystery. So frustrating. Do you know of video editing software that is more reliable?
My display adapter Intel® G33/G31 Express Chipset Family
And, if it matters, I have changed NOTHING in my computer system before this problem surfaced again.
And I have completely uninstalled and reinstalled the entire software 3 times today.
THANKS for any help you might offer.
