Long time forum surfer now a new member. I have recently acquired sportworld (C8310) basically for the pacer option, although other options look very interseting and having fitted it into my track i have the following problem. My track is approximatley 86 Feet in leng and due largely to the loft style is an anticlockwise layout. When starting in default mode both cars work, upon altering the direction of travel on the unit Lane 2 will not run, pushing the car across the unit results in SLOT NUM showing on the display. By some good luck i have managed to get the car to run occassionally but when it came off it was some time before power was restored. If i put lane 1 to N in lane used mode, Lane 2 works and upon reversing Lane 1 to yes, nothing. When running from computer, starting the race in clockwise, moving the cars a short amount and then changing to anticlockwise most times gets a result. Convinced i have overlooked something simple here and look forward to suggestions. Thanks.
