A few weeks ago this was working fine. But now, when I click the "import music" button on iTunes the iTunes totally crashes and exits out. I found out the problem, that if you have anything to do with the "sharing" folder it crashes out of whatever I'm working on but i have no clue how to fix this.

I have tried to delete the "sharing" folder, but when i try that it also crashes out of the folders and won't delete.

Does anybody know how to fix this??
If you do and could tell me, that'd be sooooooo much help!! TY in advance.
