I had to re-install the PMDG 747, but when using the LevelD767, the engine gauges were missing/black. So, I un-installed the PMDG and the LevelD gauges remained absent. A Windows System Resore Point, brought back the gauges to the LevelD767..So, as I want to re-install the PMDG747 again, does anyone know why this affects the LevelD engine gauges and what to do then?Regards,Marcelo Wachtel Santiago, Chile 11.25am EDT
