Error code: BLZBNTBGS8000000E (500)

Running X.6.8

Other Mac user accounts cannot log into (and, therefor, Hearthstone), only the one I originally installed 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 app, Shared folder, Hearthstone and enclosed folders
- removing the folder from /Users/Shared
