Hi. I downloaded it but when it asked for my ebay username + PASSWORD (!!!) I backed off. They should not need it to find your items. Auctiva doesn't ask for it in order to import listings.
Maybe I am being paranoid but I have just experienced a case of identity fraud where the crook used a stolen ebay ID to rip off a few sellers.
Like the idea though so if some reassurance can be given it would be much appreciated.
Regards
Steve
