I was just on itunes, I came off and when I clicked bak on it again it says some of the files are missing, so it can't run and needs to be reinstalled. Please, please tell me I haven't just lost all my music. I fear I may cry if this is true.

Also, it's saying I've run out of memory and won't let me save things, but I know I've got space on one of my other hard disk things. However, it doesn't seem to want to let me put anything there.

Anybody care to help with my technological woes?
