ggf162: Well, I tried it again for the 4th time and it mysteriously worked. Yeah, no idea what went wrong there.
EDIT: I'm at another impasse. The only way I can pay is with my Paypal, but the e-mail I use is the same as the age restricted account
*cries*
Might not matter. If it does, change your email to a new account. If your email is on gmail, just use a gmail alias by adding "+greenman" to the end of your normal address. ie: you@gmail.com becomes you+greenman@gmail.com
Note, that trick wont work everywhere on the web, only places that accept "+" as a valid character in an email address (which it is). Sadly many websites write their own email address validation code and have no idea what they're doing and don't follow Internet standards so this type of email alias wont work everywhere. It works on greenman though (for me). :)
