Connection Lost

Title: Connection Lost

Version: 3.1.2

OS: Windows 7 64x

Java Version: 7.0.70.11

Description of Problem:

I'm having trouble with this problem that I can't connect to my own Minecraft Server with the TechnicLauncher.exe. I get the message "Connection Lost. End of stream."

But, I'm not having any troubles connecting with the normal Minecraft.exe program.

I've tried deleting the "lastlogin" and "launcher.properties" from the .techniclauncher file, with no success.

Error Messages:

Connection Lost. End of stream.

Error Log:

Is it only me that's having this issue?? Or can the TechnichLauncher.exe simply not connect to any multiplayer server?
