When I logged itno the Developer Member Center systems says "You’ve already agreed to the Apple Developer Agreement". Even after I click Member Center it didn't work. What should I do?
Unable to log-in to Memeber Center
Does it happen with this link?
That should take you to your account summary, but if that doesn't help then tell what you're trying to do and maybe we can help further.

I am also having this error, have tried reseting passwords, updating and change appleid and everything else I could find. None of it works.
This workded for me (from stack overflow):
The problem is that you haven't verified your email address with Apple.
Go to https://appleid.apple.com/ and log in then sent another verification email.
What did you do to resent the verification e-mail? I can't find a link to it.
