Run WoW
Log into toon
Run Honorbuddy (You can also run right after running WoW but you must have a toon in game before hitting start)
Start Honorbuddy
1) Make sure you are using the latest version of Honorbuddy (4991)
2) Either use Task Manager to check and make sure there are no "ghost" versions of honorbuddy running. If there are, kill them. Rebooting your computer will do the same.
