I did everything as the manual said. And when i spawn the fmc has a red "0." written in the FMC and the FMC buttons don't make any noise as usual.
And i can't write anyhting in the FMC . I've noticed some problems with the throtthle sound when i put it on TOGA (that sound is missing now). And no i don't have FSUIPC beacuse suddenly FSUIPC crashes FSX and i can't repair that either. And those problems suddenly appeared without installing anything. Please help me!
