normally my Honorbuddy works I start wow, log in to my char open in Honorbuddy logging in and it says You have not selected a valid instance of WoW to attach to! Please restart Honorbuddy and choose a valid WoW instance to use Honorbuddy. why
What is your WoW client version ? Are you using the last version of HB ? Is your WoW client fully downloaded ?
I'm having the same problem, wow is fully updated, and I'm using the latest client of HB, what to do ?
I get the same problem, usually running WoW in max window, or just restarting WoW & HB does the job...
