Tekkit Server Bug

Every time I try and log onto a Tekkit server it comes up with the message: "Failed to login:bad login". Does anyone have any suggestions?

You are trying to connect to a premium server without a premium account?

Im sure that normally if you try to connect to a premium server with a non premium account it will come up with a different message. But you could be right

Wait. I'm sorry. If the account wasn't premium it would say Failed to login: User not premium
Failed to login: Bad login means that the password is wrong or someone else has logged into that account
