bangoops

It says the server is on 1.5.2, but tekkit lite is on 1.4.7. So what happens now?

Never mind, don't read that last comment I just posted

I can't join, this is what it says Failed to verify username, session authentication server unavailable, I don't know what to do

never mind

Is the ip the same

Can I join, my minecraft username is bangoops, also I can get videos of the server on youtube, if you want
