I have downloaded the FSX version but I cannot change my altitude, heading or speed on the mcp. The other switches on the mcp work fine. I get the plus and minus next to the knob controlling the input but nothing changes. I have reinstalled the program and downloaded and installed the latest FSUIPC but still no effect.

got it working had to uninstall and reinstall the ifly 747, last time i just tried to repair the installation. I also downloaded the ifly 747 again just in case the last one was corrupt.
