AIB, have you tried maybe clearing your cache? I'm no computer expert, but that's what my boyfriend tells me to do whenever something doesn't look right.
If you have internet explorer as a browser, go to the top of the screen and open the 'tools' menu and select 'internet options' - choose 'delete files', then 'delete cookies', and probably 'clear history' for good measure.
What this does is give your computer permission to purge all the stored 'stuff' about webpages - you know, like when you go to ebay or auctiva and your username is already filled in? Sometimes, even if you refresh a webpage, you're looking at your computer's 'stored version' of that webpage, and not the actual real-time version - clearing the cache (cookies, files, etc) lets your computer get at the real-time version if it happened to be stuck on the stored version.
All this aside, it may be auctiva issues, as well. Either way, best of luck
