My friend deadmau5 has this SQLight error almost 90% of the time he joins a server.
This is normal, it happens to me all the time.It always fixes itself when you try again.
It seems to be working for me... When this happens, I just type my authentication key back in, exit BL, and restart it and it works.
Something like this just happened again for me.
