The filename you gave is actually a build with “service pack 1” applied already. You can tell what service pack is installed by examining the filename you download from us. The “nv2.0.1….” is the clue. The first build we released was “nv2.0.0….”. The next build placed on the web with a service pack installed will have the name “nv2.0.2…”.
Hopefully that clears up any confusion you had regarding this. When you download new builds, you do not need to re-register the product.
