Welcome to Subsim Matey
The GWX that you are d/l via torrent is version 1.0. Once you have that installed, d/l the patch 1.02 and install that.
When you are patched, take a look in the program folder and you will see a folder called MODS, in there you will find GWX compliant mods. Double click on the JSGME icon and you can then load these mods, if you so choose.
I suggest, that before you try any of the great mods available here, you see what GWX feels like in it's default state.
Good Hunting.
