Version 5.0.3. is the only one with multiplayer capability. In order to run it off a personal server, you will have to add the -LAN text at the end of the .exe filename by creating a shortcut.
Example below:
"C:\Matrix Games\Starshatter The Gathering Storm\Starshatter-TheGatheringStorm.exe" -LAN
Just be sure the -LAN is OUTSIDE of the quotation makes when you edit the shortcut path.

Teach these new disciples to obey all the commands I have given you, and be sure of this, I will be with you always even unto the end of the age. Mathew 28:20
