I have tried everything to get the AP function to work. I have set the IRS switches to align, waited until the lights extinguished and put them to NAV.

I have set all the panel exactly as Bob described in his youtube vids. Set the FMC as per the instructions in the stickied tutorial and still it wont work. I have also read all 5 manuals.

It wont auto take off. It wont follow the fmc when I hit LNAV and VNAV and I cant change heading when not using fmc (and I know about right clicking the knob). It wont even hold altitude, just climbs and climbs.

I am using it in FSX SP2 and 32bit vista and have also reinstalled twice.
