I see your order in the site's database for the yearly sub. It's showing a status of "Review" and I haven't received any notification or deposit from PayPal yet, so I checked into it further. I found this page on their site.
According to that, they try to complete the transaction within 24 hours. They either let it go through or reverse it. Once it goes through, your login should work.
Kind of weird - I've had a couple of weekly subs come in over the past few days and those just seemed to happen without any delay. I'm guessing it's because you just set up the PayPal account at the same time. At any rate, we'll see what happens tomorrow. I'll be on here at night again as usual.
