"The iTunes library.itl is locked, on a locked disk or you do not have write permission for this file." Already have Full Control
Suddenly, out of no where, I cannot open iTunes. This message comes up every time. I have checked all permissions and they are all on Full Control for all users and Groups and I am the Administrator. When I uncheck the property of "Read Only" and go back to see if it took, it always reverts back to Read Only. What is causing this?
