What version of Premiere Elements are you using and on what computer operating system?
Is this a "it worked before but now" problem or "it never worked before" type?
This has all the ring of an Adobe Licensing Issue, and I may have the perfect Adobe document for you to check out
to resolve your problem.
Please let us know if that works for you.
Even though you see Photoshop Elements in the header of the article whose link I posted for you, you will see as you read on that the information is directed to Premiere Elements as well as Photoshop Elements users.
