Could you please explain how you fixed it?

 

Follow this tutorial on the Wiki.
I also got some help from this guy.

 

Again commenting for anyone who sees this thread, for a much better alternative to DS3_Tool/MotionJoy for PS3 to Xbox 360 controller emulation please see my other post here: http://www.beamng.com/threads/3650-bullettime-set-via-Controller?p=44621&viewfull=1#post44621

I was trying to spread the word under a few of the PS3 controller problem threads, I hope it isn't seen as some kind of spam and instead as help.
