Error message

[mvlazny]

Hello,
Frequently when I go to open a photo in PSE 6, I get this error message:

The photo “_MG_1511-1flwrs.jpg” could not be opened, because the original item cannot be found.

Then it offers to find it. I say ok. And then it can't be found, even though I know its in there.

Any ideas?

Thanks,
Maggie
