Unauthorized user

O.K.
So having not being able to get the launcher to work and just getting a black window opening I uninstalled it.Now when I go to install it again to see if that helps it tells me I am not the authorized user. Really guys this has been frustrating.I have rolled back drivers tried all the suggested fixes and I read here the the Beta is not being supported anymore.I don’t want a refund but would like to play the Beta!
