@tbarat: Sorry we missed your question. Greg is right, it is better to join the visualmicro.com forum for questions and help because we do not get automated notifications of questions for this page.
To answer the question (I think):
The plugin does not use Visual Studio "New Project" templates.
Please look for the "File>Add>New Arduino Project" menu item. Alternatively if you right click the "Solution Explorer" the "Add" menu also allows you to add a new "Arduino Project".
