Need help with launching Hexxit server

[ThatStrangeNoob]

Hello.

Whenever I try to launch the server via launch.bat (on a Windows computer), it... pauses without starting up the server.

Currently my launch.bat is unmodified, as shown:

java -Xmx3G -Xms2G -jar Hexxit.jar nogui

pause

And this is my ForgeModLoader-server-0.log:

I didn't know what ForgeModLoader-server-0.log.lck was, so I opened it and it was empty.

A response would be much appreciated.

Thank you.
