Well, basically, I can't login the actual beta. I'm pretty sure I typed everything carefully. Oh wait, this just popped on my mind, do I need to register a new account for the beta?
Thank you for your speedy reply sir, but (and sorry if this is a stupid question) why an invitation code? I am already in the beta, I just can't login. If you gave me an invitation code, does that mean I need to clear my cache and cookies and go to the beta site, then write the invitation code, and all will be good?
