What was the computer's video card/graphics card when Premiere Elements 10 was working for you in Windows 8 (presumed 64 bit)?
Have you had the opportunity to try to work with Premiere Elements 10 in this new system with the NVIDIA GeForce 750Ti?
There is a marked workspace change seen in comparing version 11 and 12 with versions earlier than 11.
Essentially the principles remain the same, but those features do move around, get modified, or are discontinued.
Definitely go the tryout route before any thoughts of purchase in order to assure the program's compatibility with your computer environment
and your source media..
Thank you.
