Ok, now I am piss.. After the Service pack 2.1 the 757 with AES do not work properly, every time you do a push back operation the aircraft crash into the ground with the front whell and the front of the airplane.

Do not tell me if my AES because it work with others aircraft´s also I unistall Captaim Sim 757 2.1 and put back 2.0 and then AES work, unistall 2.0 put again 2.1 and them the same problem happened again.

I hope a answer on this..

Thanks.
