I have 37k files, win7 64bit. I am able to send pictures to PSE 10 for editing. However, I am unable to use the "Edit In" fucntion to send a viseo to PRE 10 for editing. When I click on Edit In I get a list of PRE 10, PSE10 plus a bunch more (see attached screenshot).
As you can see, it is grayed out.
Any thoughts why this does not work?
Thank You in advance.
