Hi Colin,
Unfortunately I am not very proficient with the StarterKit as it is another project from the one that I am working with. I have also never used Visual Web Developer, I use the full blown Visual Studio.
If I remember correctly, the templates (StarterKit files) are extracted to your My Documents\Visual Studio 2005\Templates...
In this folder there are multiple folders for each type of template:
- ItemTemplates (i.e. Modules, Skins)
- Project Templates (DotNetNuke framework etc)
Check and see if you have anything similar on your machine.
