I also have the x-live version of the game. Despite my lazyness, i learned how to mod the game(nothing too serious, just more att. point, better wargear). Well, all my effort was in vain, because i can't make the game accept my mods(i can't do the -dev stuff and of course i dont have the rev ini file) I suppose there is no hope for me, but if anyone have a solution, i'll be happy to hear it.
Have you tried editing the shortcut to have -dev at the end of the target?
If you have no idea what I'm talking about, go into the directory, right click the DoW exe, create shortcut, right click > properties on the shortcut and where it has "C:\Program Files\Dawn of War 2\DOW2.exe" put -dev at the end.
