Gentlemen,I bought Acceleration today and installed uneventfully. FSX loads fine but if I select any of the new aircraft of load a scenario that uses a new aircraft, I get the Fatal Error Occurred message and sim quits and reloads. FSX ran great before this.I am running an E6600 with 4 Gigs mem and a GTX8800 video card. I am using Vista Ultimate for op sys.Any suggestion? Thanks

Do you have any add-ons installed? In particular, try temporarily disabling any add-on DLLs that these installs load by commenting them out in your DLL.xml file & see if that solves the problem. Then uncomment them one by one to find the applicable faulty DLL / addon.If you have FSUIPC, download the latest version (4.20):http://forums.simflight.com/viewtopic.php?...e7582f0597d5176 - regards, SkyDrift
