   XNA versions
  I was watching XNA videos from 3dBuzz, but they are using version 1.0 refresh and C# 2005 express, i got XNA 3.1 and 2008 visual studio, do I need to get 1.0 refresh to do things in they videos or 3.1 will fit in?   
  No.  Use the 3.1 version.  It is several versions ahead of the 1.0 refresh, with plenty of new features.
