Hello, I had received my beta key and activated it and downloaded the client yet when I try to log in it gives me error code 201, what can I do to fix this so i can enter the game? I'd appreciate all the help I can get!

There are no betas at the moment, and we don't know when the next one will be, so there is nothing for you to access.

Your email will have the details of who and where to contact and ask further questions, these forums are not that place.
