WAAAAAAHHH~!

I have Photoshop Elements 5.0, but the Editor won't open! Can anyone tell me why?! And, of course, this happens at the same time I lend the disc to a friend and probably won't have it back 'til Wednesday at the earliest. TToTT

PLEASE! If you know how to fix this... PLEASE tell me!!!

EDIT: Nevermind, I think I fixed it. I can only access the editor if I open it as an admin.
