It's MCL-21713 - one of my attempts to do a reinstall used the beta 2.3.508 launcher for Windows 7/8 and it's the SAME issue that has been going on at least since the short-lived broken 2.3.481 launcher.
I am not sure at this point if it is an issue with the launcher, or an issue with the auth servers, or an interaction issue between them.
Does anyone know of the auth servers (or PART of the auth servers) are located in the Microsoft Server facility in Quincy, Washington? I'm LOCAL to that area and on the same Grant County PUD fiber optic setup that facility uses.

Thank you for your report!
