I've cleared the cache and settings folder and even went as far as deleting the entire honorbuddy folder and reinstalling fresh copy of the updated .557 version. When I log in with my key it just stays at logging in. Honorbuddy v2.5.6948.557 started. Logging in...
This has happened to me before, it happens after HB crashes from loading wrong profiles etc... But I just logout and login to a diff character and try HB if it doesn't work I just close wow.exe and try again. Then it usually works
Thanks for the reply @Phazekiller but it was a different issue. My antivirus/firewall blocked the connection on me without my knowledge all fixed now.
