Without thinking, I updated my iTunes software before realizing that the new version is supposedly file-sharing restrictive. Is this going to affect all of my iTunes music files?! Does that mean no one can access my music files?! Is there a workaround -- moving files or copying them in the Shared folder? I don't want to lock anyone out. I haven't lauched iTunes since the upgrade. I use LimeWirePro. Help!

Thanks!

P.S. Newbie question: Why does LimeWire disconnect so often?! Drives me nuts.
