Renew NAV 2011 with 3 licenses to NAV 2012

12 months ago I purchased NAV 2011 from a retail store with license to install on 3 pc's, which I did.

 

I just upgraded one of them from NAV 2011 to NAV 2012 online, but the RENEW option seems to point me to information that implies upgrading ONLY ONE pc for $39.99.  I want to renewall ALL THREE pc's.

 

How can I do this online, or do I have to purchase a retail 3-license CD at local store?
