Exporting Red Faction Guerrilla textures?

I didn’t know where to put this question, I hope this category is ok. I tried to export the textures from Red Faction Guerrilla so I can use them for mapping.

First I tried to use 3D Ripper DX. But since the game starts through a launcher it fails to recognize the game process. So I would have to use the global system monitoring mode. It only works with 32bit systems - I have a 64bit system.
Next thing I tried is TexMod. Same problem here - it doesn’t recognize the game.
The last option I seemed to have was exporting the files with tools for the game. Extracting the archives worked but the texture editor does only work with 32bit systems.

Is there anything else I could do (apart from asking someone else to do all that work)? Any alternative to 3D Ripper DX or TexMod?
