Just bought a 1 day license as well as a 1 year one after having this issue. I can't auth when starting the bot. Tried both username and e-mail. Password is correct as well and I tried changing it on the buddyauth website already. Key is being displayed as unused/inactive there (until the first successful auth I guess?)
