She probably lost her files the same way I did, with using something other then the default download where it deleted entire directory. That problem is fixed in latest version. Everyone should make sure they have the latest version. Remember your files you have downloaded are stored in a list under your account and you can just simply download them all again. I know I have done this a few times as I was stupid enough to wipe out my files more then once

. If you use the list you don't get charged again for files that cost points.
