Hi fionamae,
That's very strange. We aren't experiencing any technical difficulties that would account for this behavior, so there is probably a process or setting on your end that is conflicting with the functionality of the Auctiva software. If you are still experiencing this problem, please contact our customer support team using the appropriate link on our help page, http://www.auctiva.com/free-auction-software-help/help.aspx, and we'll do our best to help you out.
