Hello,I have had the PMDG 747X for a while, and only recently an issue has arisen with this product.A few days ago I altered the VC gauge refresh rates for the 747 for better performance. Since then, all of my aircraft gauges have frozen up at various times during my flight. Once it was just before touchdown, another time I was on approach, and another time I was at cruise. My gauges simply freeze up, and no longer function as they should. On one occasion, I noticed that I could no longer change any switches or dials at all (i.e. the light switches on the overhead). One of these instances was followed by an Out of Memory error, however, I don't understand how this is possible, because I have flown the PMDG in excess of 10 hours straight, with no issues, yet, I got an OOM error after just 20 minutes in the air.Also, today, I loaded up the PMDG, and I got an error message saying: Gauge: no loading gaugeError: Panel Background (1024) bitmap not found:"SimObjects\Airplanes\PMDG747-400\panel.VC\747.CDU.bmp"I went to the location specified, and sure enough, the bitmap was missing. However, even with the missing file, I started a flight just for kicks, and the panel background appeared just as it should, and all appeared normal. So...I tried to do an complete uninstall and reinstall of the PMDG 747X, and that didn't work. So...I tried a complete uninstall and reinstall of FSX, and that didn't work either! I'm really stumped on this one, especially why everything is suddenly going haywire on me after almost a year of no problems.The only software change I have done recently was upgrade to REX 2.0, but I believe that I have eliminated REX as a problem. After reinstalling FSX, I tried the PMDG 747 without REX, and I still am getting these errors.I am running the PMDG 747X on FSX+Acceleration with Windows Vista. My computer specs are in my signature.Thanks, Ferrari

I'm  having the same problem, someone please help
