It's like the file associations are getting lost. The image files are still there in the folder, but they don't show up in Skinstudio. The default files show up...or nothing at all. Sometimes there aren't even any sections for the normal parts of the skins, and I have to add them manually.
I lost the whole start menu tonight, plus the taskbar parts. The window sections were all there just fine though.. This is really upsetting because I'm trying to get a skin ready for the GUI Championships and if this keeps happening, it's not going to work.
And no, I haven't started a new skin. I've been trying to recover all of the one I was working on.
