When I try to open iTunes, an error message (not named) comes up that says iTunes cannt be opened because the folder "iTunes" cannot be found or created.  Then it says the defalt location in in the My Music folder.  The iTunes folder is there but the program still won't run.  I resently tried moving the music to an external hardrive and thats when the problem started, but I moved it back and nothing happened.  I can't open itunes at all to fix the problem.  Please help!  Thank you!
