I recentlybuyed the CX for FSX. I have a bigproblem with this airplane. The planeflies nicely with either FMS or hand controls and suddenly, after 20 minutes, engines cut-offs (theplane seem to be in cold n dark mode) I can't doanything; the throttle is lock in cut-offs position and all switch are freeze. The plane flies without engines until the crash . I have aregistered version of FSUIPC and fuel is ok. Any help willbe appreciate. (sorry for my english)
