Hi Al,
You can schedule a Closed Listing for Import from the Closed Listings page. Note, it isn't an "instant" process. They also automatically imported some of my closed listings at sign-up.
Auctiva does add the Scrolling Gallery to all active listings at the point you sign-up and pass the Token with eBay. That's a one-time process for a new account. It also populates your Auctiva Store with your listings. Did that happen for all your Active Listings?
