David,Check your scenery.cfg file and look for any possible corruption (i.e., areas/layers not in numerical order; missing numbers). ScanAFD may have gotten rid of duplicate sceneries and now a config file (aircraft.cfg/scenery.cfg) is calling for that scenery texture and it's not located in that folder anymore causing a crash. I think those files you are referencing (such as C:Documents and SettingsMy NameApplication DataMicrosoftFS9CFG.TXT) are the documents gathered up and sent to Microsoft for troubleshooting purposes. I don't recall anyone getting an error msg such as yours. Usually the error will reference a ".dll". Check your Event Viewer (if you haven't already) and look for causes of each crash. Hope this helps and you can get it resolved soon.Best Regards,JimYoung
