.prel file will not open in premiere elements
Hello,
When I attempt to open a .prel file, this is what happens:

If I click a file this box comes up:

If I just hit cancel, the file loads with this message and is unplayable:

Does this happen because I deleted all of my raw video footage from this computer? It still doesn't work even if the raw footage is on the same computer. Does the raw footage have to be in a special folder? Is this happening because of a version update? Will I ever get this .prel to open again.
Thank you.
