Hello, I bought the PMDG 737-6/700 a while ago, and it has worked fine up to this point. For some reason, I press the AutoThrottle hold switch and it won't turn on! And then I get a little red error button (http://img.photobucket.com/albums/v141/shortstopmmc/untitled2_tHNYe.jpg) go there^ ^ and it is on the bottom left of the picture.Any help/suggestions?

Make sure your engine generators are on, as well as the engine hydraulic pumps/etc...check the overhead for errors.-stefan

Don't I feel stupid! Thanks!

Hopefully you aren't pressing the autothrottle until you are holding short of the line...Dan Ward
