there is a separate forum for Premiere Elements at
I suggest that you look over there. They have a Premiere Elements FAQs section posted over on the right hand side of the thread listing. So I suggest that you look at those FAQs and if you don't find your answer there, then post in the main section of the Premiere Elements forum.
Also if your computer has a Nvidia video card there is a banner at the top of the forum with specific info.
