satellite tracking with the Meade LXD 55 (ISS)

I need some help with getting the mount to track the space station correctly. I input the orbit info by hand so that it is correct and up to date. (I heard that the autostar will not update ISIS properly) I align the mount get the pass info, the scope slews to the position, and when I push "enter" the scope will not track. It hardly moves. It does move but in no way to track the station. The battery power is fresh so I do not believe power is the problem. Any suggestions?
