Error code: BLZBNTBGS8000000E (500)

Running X.6.8

Other Mac user accounts cannot log into Battle.net (and, therefor, Hearthstone), only the one I originally installed Battle.net with. Does not ask for my Authenticator when putting in my log in information. I have tried:
- fixing permissions with the OSX install disk's Disk Utility
- adding user read/write permissions to Battle.net app, Battle.net Shared folder, Hearthstone and enclosed folders
- removing the Battle.net folder from /Users/Shared
