Hi, I can't remember the last time I was able to fly the default FSX C172 but now whenever I click on it to select it, FSX crashes. I don't know why! I don't really want to have to run the FIX disc that came with FSX because last time I did that I had to completely reinstall FSX and ALL my addons because it stopped working. I don't know if it was because I didn't run the FIX disc for Acceleration or what. But anyways, any suggestions on what I could do to make the Cessna work again?Thanks,Jeff Smith

The FSX C172 is not a PMDG product. You should post this question on the general FSX forum, a lot more people frequents that forum and you will have better luck getting it answered.

Try deleting your default flight files in Documents/Flight Simulator X Files and rebuilding your FSX.cfg...
