MotionStar Position Tracking

[starlingstm]

Hello, I'm trying to capture my real-time movements in motionbuilder using motionStar. I am able to record a t-pose and attach the markers to the ankles, hip, and the head with successfull tracking (the head and hip are oriented). However, the wrists sensors are not attaching to the desinated markers. Once I go back to the live state everythings tracks correctly but the arms; I get no movement from the arms, the sensors are still floating mid-air and there are small white markers located on the wrist. Please help, I gone through the other post.
