Jill, I hate to ask this as it irritates the devil out of me, but have you cleared your cookies and cache. If not I would do that. Also are you using either internet explorer or mozilla foxfire for your browser? If you are using say chrome (which I LOVE) auctiva does not I think the word is "support it". That may be wrong wording, but the other two they have refined more.
If you clear cookies and cache, close all of the browser windows except one. Then clear, I usually then close that window and then log back in. (however, if I were you after doing it I would just re-start just to since you are that close anyway.
IF that does not work I would send support a note, stating that you have cleared cookies and cache, if you do not put this, I would bet that will be your first response back, so this will save you one step.
Sorry I could not help more, I was just hoping it could be one of those.
