I bought honorbuddy for one day to try it, i minimized WOW then i had to restart it.. When i tried to logg in it said maxium seassions..
Yup, restarting the bot sometimes keeps your session logged for a short time. Just wait 5 minutes and it should be good.
register here Home Page - Buddy Auth Portal using the same email u used in checkout page and next time you will get that error,login and kill the session in use
