MCDzienny

I recently set up an MCDzienny server to play around with, setting up game modes, usual stuff.
All went well the first few times I ran it, friends were able to join using both ClassiCube accounts and Mojang accounts.
After some time I had issue when trying to set up a second server, I downloaded the software again but it never asked for an update when I ran it (I also ran the updater.exe countless times); I checked my firewall but nothing to see there.
I finally managed to get v11.0.0.0 from another computer and put it on my hostcomp. I now have the issue that only ClassiCube accounts are able to join the server. My first MCDzienny server is experiencing this issue too.
(Oh and if you are wondering why I didnt just duplicate the first server (which already was on v11, thats because it was setup as zombie and putting it to lava, which I wanted, gave me an error)
Did I miss out a configuration?

Thanks in advance.

Sorry, I didnt see the option to edit post.
Players from ClassiCube trying to connect now also disconnect, reason: Authentication failure.

Are you trying to host your second server on the same port as the first one? That might be the problem, then you would have to make a new port, also make sure you enabled "Verify Names"

No I am not trying to run the simultaniously on the same port (one is on 25565 and the other on 25566) both these ports are forwarded. Verify names is also checked.

You mentioned there was an error, can you post it?

I received this error trying to switch between zombies and lava survival on my first server.

However I am able to join this server, though only with ClassiCube accounts.
