Does anyone have a copy of the post from the old forum with instructions for installing Wurm behind an HTTP proxy anywhere? Mostly I think I just need the command for installing all the downloaded jar files.

This thread?

Yeah, that mostly did it, modified the batch file there to use the correct versions and download current files and got the launcher to at least come up. Now I just need the URLs for the graphics.jar and sound.jar files so I can get them downloaded.
