the payment page keeps asking for a valid email - which I have done...I thought that I would let you all know.
I do have quite a simelar problem today.
I wanted to register and bye a ticket for the uncon. After filling out everything it told me, that there is already an account on my email adress and that I entered the wrong password. I thought this was wired, because I cannot remember. Than I wanted to reset the password to get a new one and now the page is telling me, that my email adress is invalid and I should enter a valid one. Which I have done several times now without succsess.
I do not think that I am registered now, I will try again another time.
