Tell you what. Enter a Support Case at the HELP link above (lower right on new page) and tell them you just joined Auctiva and have 100+ listings in the update process for the Scrolling Gallery. Tell them you'd appreciate anything they can do to speed-up and watch-over the process at eBay. I'd also ask about the listing IMPORT process, so you can get old listings updated with templates, etc.
It never hurts to ask.
Hopefully, you'll wake-up tomorrow morning with a Auctiva Store full of items.
Make sure you understand the Auctiva Insurance plan (I recommend) and their checkout process before you decide to list. You can opt-in or opt-out of both.
