I copied some backgrounds onto my 8900 using the media manager, but when I decided that they weren't coming out as nice on my BB, I deleted them using the USB mass storage mode (E: drive on my windows file explorer). Now I have icons when I go to Media>Pictures>All Pictures, which I cannot open through my BB with this message:
"Unable to display file
/Media Card/BlackBerry/pictures/2.jpg"
and I can't delete the file either. It just asks me if I'm sure if I want to delete and it just comes right back to the All Pictures Menu
