Hi Thomas,
I tried to put through an order in IE to see if I could see what you are seeing and it went through fine.
Please delete order #6 and VOID my card before 12 tonight (otherwise it will cost you to refund! ;) ).
Unfortunately the issue you are having with IE - "Session Timeout" - is probably a cookie blocking problem, with a firewall or your settings or something. It's not likely to be the cause of the inability of Zen Cart to create the order, it's just unlikely that anyone would not be able to put their card details in on time before the session times out.
I wish I could be of more help but I really don't know what else to say. :|
All the best...
Conor
