Newbie Question; Relationship between GWX and SH3 commander

[yatyas]

Up front let me say that if programming expertise is a requirement to make this work, someone just quietly tap me on the shoulder and I'll content myself with the stock game.

I've been to game shadow, atomic gamers, and many other links. The GWX 2.1
manual on http://gwx.mysite.orange.co.uk/ is a dead link for me. This page also lists a bevy of mirror sites that have multipart "megauploads" for a .exe and many .bin files (I type that like I know what a .bin file is) and I'm confused as to whether any of these are what I need to d/l.
The Gameshadow site installs itself over and over but never finds GWX. The Atomic Gamer site has 8 different expansion mods for GWX. so I'm guessing that aint it.

Clearly I'm missing something fundamental here. I freely admit that I'm no computer whiz, just a knucklehead trying to download a file and drive a sub. I don't know what a "torrent client" is, the Filefront site http://search.filefront.com/gwx2.0 has a gwx2.exe along with 7 or so .bin files, so I'm not sure which one, if any of them are what I need. Thanks in advance for any help.
