trying to buy tp, paypal issues

[Eada]

I tried buying TP using Paypal (not through a paypal account, but as a one off payment)but got the following error: "There was an error processing your request. Please try again." This was after confirming my details on the Paypal page and authorizing the payment there.

Trying again didn't help, and I've got an 'order placed' email from Paypal saying I've authorized a payment to Turbine. I'm not sure if this means the amount has been paid, but if so can anything be done about this? Either a refund or adding the TP manually is fine. I understand you guys are busy, so there's no real hurry. It's just annoying is all.

And is there any other way for me to pay for TP? I get an 'Authentication Failed' error anytime I try to add a credit card.

Thanks.

Nvm, I figured out how to add my credit card to my account. FWIW, it's through http://myaccount.turbine.com
