Do you mean you created an Ebay store?? When you sign up for Auctive, you automatically get an Auctiva store. I never even look at mine, I find it to be of no particular benefit (at least for me).
As for the browser issue, maybe you're just having a glitch? I use IE all the time with no problems, but occasionally it does get glitchy. Why not just use IE when you're working with Auctiva?
