The initial email I recieved after I placed the order contained a link directly to it. Check that email for the link. I think it's a custom link because it contains a RecieptID in it.

Quite right, Kevin! I'd forgotten all about that initial email, probably because it looked like just a receipt. But there it was in my old email. I checked it and mine shows "Issue with Order." I wonder if that's just because of the backorder status or if something else is going on. Guess I'll call them this week.
Thanks for your help (pointing out the obvious, that was apparently too obvious for me to figure out).
