2 Possibilities:
1). on your computer that you are running, make SURE you are only running "Flash Player 8", if you running a newer flash player, then.......... you WILL have issues...
2). I suspect you may need the new(er) flash plugin that was updated to run that screen set,
further (less chance of this being correct, as #1 is usually the culprit).
Slim chance it could be combo of 1&2...
Get a hold of "Andrew" at Mach Motion, he deals with implementing those screens for customers that buy it from them.
