Error loading Entity Template in VS 2010

I've just installed VS 2010, rebooted, and then applied SP1. I ran VS using 'Run As Administrator' to set C# as my default environment, and then closed VS.

I then installed the 7.2 SDK. So far, no errors.

When I try and create a new Project/Solution, or add a new Project to an existing Solution, I get this error:

Error: this template attempted to load component assembly 'SageCRMEntityWizard, Version=1.0.0.0, Culture=Neutral, PublicKeyToken=<bunch of #s>' For more information on this problem and how to enable this template, please see documentation on Customizing Project Templates. '
