nis 2011 ipod

I recently installed NIS 2011.  When I connect my Ipod, it is not recognized by windows vista home basic.  I thought the cord might be faulty so I bought a new one.  It still is not recognized.  It was recognized when I had NIS 2010 installed.  Is this a coincidence or is there some setting(s) in NIS 2011 that I need to change?
