iTunes for Windows: -3221 error displays when accessing iTunes Store

Some iTunes for Windows users with the McAfee Personal Firewall Plus installed may display a -3221 error message when you try to access the iTunes Store using iTunes for Windows. If this happens, change the permission level for iTunes and iTunesHelper to allow full access.

This should allow iTunes and iTunesHelper to both send and receive data from the iTunes Store.

More information on changing permissions can be found in the McAfee Personal Firewall Plus User's Guide.
