Itunes says "I do not have enough access privileges for this operation" how do I fix this? A year or so ago I was mucking around in my privacy and shared settings, trying to make it so my computer was "secure" when on a college network. Now with my fiddling i've screwed something up and I am running into problems with my shared files. Any ideas to fix?
To make changes to Sharing in the Get Info window for iTunes please unlock it first.

There is small lock at bottom right of that window, you will need password to open it.
