For example, I was using iTunes and it worked fine in the primary account. I then set up a secondary account (that I'm going to switch to as my primary) but I've noticed a problem where iTunes now reports that: "The iTunes Library .itl file is locked, on a locked disk, or you do not have write permission for this file." and it won't start. How can I resolve this? Note: I share the iTunes user files with the host. I believe that's the default, but since it applies to the issue I'm running into I figured I'd include this bit of information.
