Common Problems

Unable to download authentication module. Please try again later.

The game cannot log in due to corrupted cache data in the Users/Shared/Blizzard directory, or the directory's permissions are preventing the game from accessing the Users/Shared/Blizzard directory. Try the steps below to resolve this issue:

  1. Deleting the Battle.net cache folder can resolve problems with the logon module.
  2. Repair Disk Permissions to resolve any permission conflicts with logon modules.
  3. Reset Folder and File Permissions to make sure there is no conflict between the latest OS update and your permissions.
