SmartGit/Hg launch error

Question

For a personal project, I've been trying to get SmartGit/Hg to run from a portable drive. To do this, I am using the "generic" version that runs on Java alone. Unfortunately, every time I try to launch it, the following errors show up:

Since this is a commercial program, I cannot legally check any of the files mentioned for errors. If anyone has worked with SmartGit/Hg and knows how to fix this error, I would greatly appreciate any assistance. I hope is not too specific of a question to be removed from the listing since I could not find any other information on the errors.

Slight addition to information: The launcher that is being used is derived from the following supplied .sh file:

#!/bin/bash
#
# Normally, editing this script should not be required.
#
# To specify an alternative Java Runtime Environment, set the environment variable SMARTGITHG_JAVA_HOME

In my case it was not using X windows in my ciXwin correctly. I needed to remember to start my SSH with:

$ ssh -Y vagrant@localhost

I realize you may not be using the same system as mine, but that might give you something to go on!
