Adding System to SLD

Right now when I go create a model using the Create Model wizard, there is no option to select an SAP system.

So I figure that I have to add a system to the SLD, since our SLD had none of our SAP sytems set up. When I logon to the SLD via http://servername:50000/sld I click the Technical Landscape Link. Next I click the New Technical System button. Then I go thru the wizard entering in the proper information, until I get to the page where you have to add a product. It gives me no choice of product. What do I do here???

I am adding a Web ABAP system and have checked all the values to make sure they are correct...

Any advise on Adding a system to an SLD would be helpful. I've been over the documentation, but it doesn't seem very thorough
