I registered for a November 12 test on October 7 and paid for my transaction online. Apparently they received my money on that day but returned it two days later, but I didn't know this until I got my bank statement a month later.
Of course, I didn't receive any notification. They do specify which web browsers to use on their login page, but it's not obvious unless you know to look for it.
Since I registered on Google Chrome instead of Internet Explorer, I cannot take my test today at 11am because I'm not even registered. If you can access the website regardless of browser, Praxis should accept transactions, anyway.
