dimmest,
We have just placed your scrolling store window on the update list. If you maintain at least one running auction at all times, your store window will update on a daily basis. If there has been any delay recently in updating your showcase, we apologize. Your other 8 listings should be imported to Auctiva soon and once they're imported, they'll be displayed on your auctiva store window the next time it refreshes. The store window refreshes about every 2 hours.
There's no way for you to do it manually, but you can always file a support case using the appropriate link on our help page and we'll do it for you.
-Mike
