tmostad,
Geomagic V2013 was, IMO, a mistaken release. Although some here dispute it, I removed it within minutes of installing it (falling back to V2012) and was very happy when it was replaced very quickly with V2014.
To be clear, Alibre was Vxx from V1 through V12. It then changed to V2012 -- apparently to avoid having a V13 release. Thus, V2012 = V13, V2013 = V14, and V2014 = V15 -- and V16 would, in that sequencing, be V2015. There will be some confusion here, but I believe that the Vxx designation is really much cleaner as versions should not (IMO) be tied to calendar years!
I have only just now installed (Geomagic Design) V16. I was in the middle of a project using V2014 (V15) and could not risk any hiccups. I have yet to find a problem with it, but this is a statement made after less than 2 hours of install testing. Reports here are mostly positive other than the furor over the change in license server changes. I would highly recommend making the upgrade as V2013 was, as I said, a release that should never have been allowed to see the light of day.
