Force Feedback?

I cant seem to get Force Feedback to work. I have selected the pip but im not getting any results. Im using a logitec force 3d pro

Hmm so far it seems to work fine but our ability to test such a hardware specific feature reliably is very limited...

Hmmm. I dont seem to know whats going on. I have the drivers loaded up, and the computer self test has them working just fine. Im at a bit of a loss. Im really enjoying the game even without force feedback. You guys did a hell of a job!
