Trying to run TSE in multiplayer mode

Hello,

I changed the example in the demo to load a newMission.mis file (created in the editor - just picked "new mission" and then saved it) in multiplayer mode in demo\client\init.cs:

changed:
createServer("SinglePlayer", "demo/data/missions/features.mis");
to:
createServer("MultiPlayer", "demo/data/missions/newMission.mis");

I started a dedicated server for that mission and then I tried to connect with a client. Starting the client I entered "canvas.pushDialog(JoinServerGui);" on the console, selected the server I started before and then entered
"JoinServerGui.join();" on the console. The mission started to load and then failed with an "Invalid packet" message.

Can anyone help me with this? Thanks
(The logs were a bit big to paste here... I posted just what I thought was important - If the complete logs are needed I'll post them)
