Unregistering on Mac

[saral22462934]

Hi I've been trying to unregister Adobe digital editions with my old id so I can register it with my current one that is associated with my Nook, however it keeps telling me it's unable to do this at this time and to try again later. I've been trying for 3 days and have in it nstalled and reinstalled twice with no luck. I tried the Adobe support on Twitter, but they just sent me here is anyone able to help?
