Marketpress 3.0 latest version

I am upgrading to the new 3.0 version of marketpress, have the newest version installed, and fighting with reconfiguring – it’s not a fun experience at all. My biggest problem right off is…the new cart is collecting shipping information on a free digital product. in 2.0, it would just need an e-mail address. I can’t figure out what I have set wrong, as far as I can tell I have set up the site in the multisite setup correctly. I can check out providing name address and everything, but I want people to be able to just provide an email like they used to. What am I doing wrong?
