lately, i see the same issue. sign-in to use my mac and my one windows computer is recognized by adobe as two different computers forcing me to sign out of my mac and into whatever version of my one win computer adobe cc things i'm trying to use. then if open a different adobe app (especially if it's not a cc app like captivate), i'm prompted to sign in to "that" win computer.
still trying to work out what it's doing.
I solved this issue via Adobe support with a remote session, there is a folder called Adobe, the one in username/documents or and another system folder - we renamed it to Adobe.Old so that it creates a fresh one and this fixed it. Seems to be a Windows issue.
