Need help patching R6 Vegas to 1920 x 1200

Ive downloaded the fix, and put it in the flder it says to. I renamed to which is a rar file. and I still dont get the option under video for 1920 x 1200. How do I manually fix this, is there another way? Just picked up this game today thinking the new 1.05 patch would have support for 1920 x 1200 but no. Now Im trying to fix it another way, anyone know? thanks!

when u downloaded the fix and put it into the correct folder it changes your resoloution automatically to 1920x1200. so when you go to the video option it wont say 1920x1200, it will say 640x480 or whatever the lowest resoloution is. so when u have it on 640x480 it really at 1920x1200.
