Hello everyoneI've read alot about CTDs in FS9 here, but have held off posting until I'd read through them. However, none match the circumstances in which they have been occuring for me.I get CTDs when using World>Airports>Go to Airports and also when switching the time of day. This has only happened recently, and I think since I installed the CH Throttle Quad. That meant I also changed devices.cfg and had also done a tweak to FS9.cfgI've updated DirectX, my ATI card drivers, deleted backup scenery.cfgs, run ScanAFD and FlightSim Manager across my setup, but still they happen!Can anyone offer any advice/solutions?Many thanksRob

You mentioned a tweak to the FS9.cfg--one thing to try would be a "rebuild" of the FS9.cfg--you rename your current one with an extension of .old or .bak, and start MSFS. A new .cfg will be rebuilt, which is usually (but not always) optimized for your most current equipment.I do find suspect however that you're having an issue when you change the time of day. Do you recall adding any textures or moving any items from the main Flight Simulator 9texture folder? Many of the textures called up when you change the time of day reside in this folder.-John

Thanks for the tips John, I was thinking an FS9.cfg rebuild may not be a bad idea!As to the textures, I wonder if that may be the case. I will check - and if needs replace from the FS9 CD.Rob
