Are just interested in finding out what is happening.

I was flying with the 757-200 V1400 and everything was fine.
Bought F-Block update.. and NOW the AP is not working at ALL??

Have Alligned IRS , have input'ed info in CDU.

When you flip the FD switch, on the screen I can se Alt hold flashing ONCE.
Everytime I try to push Alt hold .. it shows on the screen for 0.5 sec and gone. >:( This is the same with VS and Heading hold.
Nomatter what I do, its INOP. And when you try to use the Z-key nothing happens.. FSX does respond on
disconectiong the AP with voice response "AutoPilot disengaged".

The AP is completly N/A

HOW to correct this problem? :-/
