Im using the technic launcher but the attack of the bteam server I cant get there because it said Failed to login : Bad Login what should I do?
Hmm. Wonder if its a technic launcher thing? have u tried using any other platform to login to bteam?
I have been informed that bteam is giving bad logins to a few players. This occours sometimes. It may resolve itself with time. Also to note, other players have resolved this issue with a simple restart of the pc. (Note : this may not work for yourself)
The issue is on Mojang's Side, as the 1.6.4 auth has been breaking lately due to the amount of users that have been using it (or so I have been informed). You just have to wait for Mojang themselves to fix the issue, as its on their side. It's happening to nearly everyone, if not everyone, so waiting seems to be the general fix of it.
It's an authentication error, you can search the forums and find that every now and then it pops up and is entirely out of our control on this one.
