Missing Files in iTunes
Did you actually resolve this problem? If so, how? If not by finding the file on your hard drive, and then updating the link in the iTunes library to it, in what way did you stop this error?
I’ve see this error many times myself, and in every case it was due to the music file being moved or deleted. I’ve fixed this by answering yes when iTunes asks me if I want to locate the file. When I did, the error disappeared.
