PR2 cannot reset after installing openni_camera

edit

Hi I wanted to use the kinect on PR2 so I installed the openni_camera using sudo apt-get install ros-fuerte-openni-camera. After doing that,I could not reset the robot anymore. The reset option on dashboard turn gray and said could not find motors service. I checked the install log file, it seened many packages were upgraded

I was using the fuerte version. When I switched the system to electric,the robot could run again, but it could not run again when i switched back to fuerte. The problem could have something to do with the upgrades . Could any one faced this problem before and have a solution? Thanks!
