Hi,
This is an Internet Explorer bug, i have the details on the site with a patch to fix it. What happened was when they sent out there last windows update to fix a security problem they had with there browser, it caused problems with some secure servers that post data to a shopping cart, like ours. So anyone that updated there IE lately will have problems on our site. *thanks MicroSoft*. I'm sure it took a big chunk of sales from us already. I have a link to the install patch on our site that fixes. Hopefully they'll put the update in there auto update they send out, because the patch is hard to find without a direct link.
thanks
