Woke up this morning and all my tunes were gone from iTunes. All had that ! beside them. If I search for the songs which were all in one folder windows can find them. The folder is called "Files From Old Computer" which WAS on my desktop and according to my windows search is still on my desktop. The folder is not there. I didn't move it, I didn't delete it. Windows thinks the folder is still there. Why can't I see it?
