Just go to my movies and rebuild database - In HE you can not see movie art, but your dealer can see it in Pro - If you still have issue ask you
dealer to delete and reload the My Movies Collection Manger Driver (We had to do this)
My Movies Collection Management is now on 5.40 and for the first time in along time no issues rebuilding database- Once sorted we now back up the data base - You can do this in HE also my Back up included art work.
I do feel your pain
