Help! Can't login because the hamachi-server rejected my login.

[cook]

Hey guys! 

I want to run a minecraftserver, so i downloaded everything I need and  I  login (for the first time) at the hamachi-program and then he says: "The hamachi-server rejected your login" 

Help me please, greetings Tim

I need help on this too. Whenever I press the power button in Hamachi, it stays on resolving for a few seconds, then attempts to log in, and displays the same message. I've tried everything, including restarting, reinstalling, deleting local Hamachi files, etc.

I really need help with this, it's genuinely annoying me.
