Problems ripping from Family Guy: Back to the Multiverse

[DecaTilde]

I recently bought the game on Amazon, and have started a Steam account yesterday. However, I'm having trouble ripping models and textures from the game using Ninja Ripper. I pressed the assigned RIP and Texture keys, but nothing's happening. After I exit the game, the RIP and texture files never show up in the output folder. I've tried using the D3D9, D3D8 and D3D11 wrappers, but nothing. And when I run the game by itself, it gives me this "Steam needs to be running" error. What am I doing wrong?
