Same problem, no help from customer support. This is a problem with the payment page, as the CC info is not being passed to the bank for verification. TT sees something on the page it doesn't like, then blanks out all the fields. This is something that might happen if you had only four digits in your zip code, for example. Unfortunately, TT doesn't tell you what's wrong, just the generic error message. One thing for sure: it's not because the mailing address is incorrect, or the CC # is wrong.
