Linux Server Problem

[Raivek]

So I have been running a server off windows for some time and decided to try unbuntu....

I've gotten the launcher and my modpacks to work fine, but when I try to launch the server using Java Web Start (the only option available) I get this error.

JNLParseException[ Could not parse launch file. Error at line 0.]

The others seem to work fine since I can choose the JDK to run them... but I'm at a loss. Any help would be appreciated. Thanks.
