Hi rosary_maker,
1) I suggest that you file a support case regarding this issue using the appropriate link on our help page:
http://www.auctiva.com/free_auction_software_help/help.aspx
2) To add the store window to your listings for which it has been removed, please retrieve your store window html from Auctiva -> Store(tab) -> Store Window HTML. Then, using eBay's "Revise your Item" form, simply paste the store window html above or below your html desription, depending on where you'd like it to appear. However, when your store window is added in this manner, the colors will not automatically coordinate to your template colors.
