Signing up for InstantCert

[supermom]

I tried to sign up for a month of InstantCert for our first time this morning. When I entered our credit card info and clicked submit, the next page said something about "Session Time Out". No confirmation at all. So I thought I must have taken too long and tried again...twice. All 3 times, I got this message. So...I'm wondering if I paid 3 times or if something is just wrong with their site?? I don't even see where to sign in to access tests, so I am guessing I have not signed up although i did pick a username and password in the sign-up process. Any idea what is going on?

Thanks,
Monica
