Red Faction Guerrilla GFWL Fix

Some people who bought Red Faction: Guerrilla on steam have run into a problem updating Games For Widows Live, and therefore could not play multiplayer.

If you are experiencing this problem, open up a run command, then:

If you have Vista/Win7 64 bit type this:
"C:\Users\%username%\AppData\Local\Microsoft\XLive\Updates\54510837\Content\rfg_updater.exe" /f "C:\Program Files (x86)\Steam\steamapps\common\red faction guerrilla"

If you have Vista/Win7 32 bit type this:
"C:\Users\%username%\AppData\Local\Microsoft\XLive\Updates\54510837\Content\rfg_updater.exe" /f "C:\Program Files\Steam\steamapps\common\red faction guerrilla"

Let me know how this works for you.
It fixed my problem.
