I cleaned my registry like you had posted in one of the threads and did the XML delete of FSUIPC,it did help with a problem I was having with the default KSEA flight where the aircraft would load not ready but with the gauges blank where I would have to set everything up! I'm not very computer savvy so you will have to bear with me as I am new to PC Gaming. When I did the XML delete and deleted the FSX CFG it helped with that problem,and the 767 takes off and follows the flight plan without a hitch,but when I try a simple flight from KBHM to KATL it does the nose up and swan dive once again.(mind boggling) Maybe someone can enlighten me on some bugs in my machine which may be causing the issue. Once again any input to fix the problem would be greatly appreciated.  ;)
