OK, finally got my card to work and now I'm a member. It actually was a problem with the card...the fraud department declined the strange foreign transaction. At least the card security works good! So we'll take away strike one and call it a ball.
But now that I'm a PAYING member, in order to get the 'premium' scenes, my credit card must "pass attestation". So, even though
they now have my money and
the clock on my membership has started ticking, I can't download the best scenes on the site, until I prove that my card is actually my card. What bullshit!

STRIKE ONE! That's what fraud protection departments at the card companies are for...damn, it worked just like it should've in my case!
So, I tried the first 'attestation', but the charge to my card for now is a generic $1.00 value until it actually posts. You only get three chances to put in the correct amount (somewhere between $0.20 and $2.00), and then you must start over.....also, you only get three total 'attestations' per card. So on my first attempt, I tried the $1.00 and it didn't work, so I guessed at the other two, and of course, neither of those worked. So, now I've used up one of my three 'attestations'.
Later in the evening, I got an e-mail about the first attempt, with a link to put in your 'attest' amount at a later time. So, I started the process again for my second 'attestation', but this time will wait until the actual transaction amount posts (once again, they already have my money and my membership time is getting shorter as I type). So currently, I have two pre-posting authorization charges on my card, each for $1.00.
Update forthcoming, after the actual amounts show up, and I try to complete the second 'attestation'.
