If you'll notice, that mod was for the PC version of the first WWE Raw game, not Raw 2. ;)
Also notice on the page that you linked to that shows how to insert the mod, I was one of the people that figured a bunch of stuff out for that game, which allowed people to mod it. I quit working on mods for the Raw games a long time ago, but used my knowledge to mess around a little bit with Raw 2, but since the Raw games got really old, really quick, and aren't that great, I quit messing with it. ;)
I think you should just wait for Wrestlemania 21, because it will be actually worth modding, and I will be sharing alot of info I find out for it. If I happen to finally find the beta version of it, I will get a head start on modding the game too. ;)
So, in about a month and a half, we will finally have a wrestling game for Xbox that will be worth messing around with, and I can not wait. :)
