problem with multiple ygf sites

I signed up @ nocc.ygf last week...Today I tried to log in to a different ygf site using the same login info but it says that no such user exists...So then I tried to sign up again but it says that my email address has already been registered...I had an email sent to me to reset my password in case that was the problem but after I did so it still gave me the same error...Any help would be appreciated...

thanks

You have to sign up for the second site and click the "existing user" button.

I DID THAT...

When you sign up do you click existing user and enter in your e-mail and password. Whats the error?
