I paid mine online last night. I was able to get all the way through, and got the confirmation page.
When I tried to get the Printer Friendly Version, I got the page not found error.
Luckily that page opened in a new window, and I was able to print out the "non-printer friendly version" confirmation page.
I did receive my email about 5 minutes after I submitted the payment, and it had all of the same information as the web page.
YMMV,
Bill
