Just downloaded the IFDG 757-200 in the Song livery for FS2002. Everything was going ok until I got to FL100. At that point I tried to increase the IAS to 300 but the plane failed to increase speed. I even tried to set it to Mach and still failed. After about Fl180 the plane began to lose both speed and altitude. Very frustrating. I was climbing at 1,300 fpm which is propoer procedure for this aircraft.
Any thoughts? Anyone else have this problem?
