Can not log on minecraft

[Coen500600]

Hey
I'm Coen (Coen500600 Ingame).
I have a problem, I can not log on minecraft.
There was an error when I cube craft join.
When I went I minecraft reboot it and I could suddenly no longer log!
I do not know if I may put it here but I thought itself; perhaps this is happening more frequently.
I myself bought a Diamond rank and cranky ... OImdat I can not login.
Do you know why it can not?
have a nice day!

Are you still having this issue? Can you post a screenshot of the error it gives you?
