Okay, so I tried to make a MAL account today, but every time that I sent an authorization key to my yahoo email account and clicked on the link provided in the message sent to me, I saw this:

"Invalid key provided or user has already been authorized."

But, when I try to log in, I get this:

"This account has not yet authorized their e-mail. [link]Resend e-mail authorization.[link]"

What's going on? How do I fix this?
