I followed Grimweed's instructions, but when I tried to save it said that there were spaces in the name (which there weren't), and that "Unreal names" cannot have spaces. I had used ACDSee32 to convert one of the existing armpatches, I don't know if that makes any difference.
any part of the filename path (C:\Program Files\Red Storm...)has to be space free. "Program Files" has a space in it. Try reinstalling your game to "C:\RedStormEntertainment\RavenShield" (without ANY spaces), and renaming all of your Raven Shield folders so that they have absolutely NO spaces. that should work
