Hello,
Because of technical limitations you can not log into your GRAPHISOFT ID account inside ARCHICAD using Google or Facebook, so it was greyed out intentionally. We are going to place a notification about this somewhere.
If you are registered with those accounts, sign in to GSID from a browser, go to your account settings, and set a password for your account. After this you should be able to log in using your e-mail address and your password.
Regards,
Daniel Alexander Kovacs
