Hi hynes123,
You just grab the top file from the patches page, I linked to, the server application (5MB)
When downloaded you run that. This will install it. You don't really need to change anything, just click through the installer.
When installed, you run the program.
And then. to set up the program, the guide I linked to is really the best thing to follow.
I hope this helps a bit more.
Regards,
Fred
