dll CTD at KDTW by Mike Magner (kdtw_v2.zip)

Hello fellow simmersIn FS9, I am using this addon, the best available for FS9, as far as I know.The problem is that I randomly get CTD after sometime at this airport (whether spotting AIs, or preparing a flight).It is mostly ai_playr.dll but sometimes atc.dllI have checked my AI aircraft textures (should not be 24bits), checked faults in the afcad and the surrounding ones, everything is OK.Does anyone know what is the most likely cause of these two types of crash? Apparently, they are related to AI Traffic.Any clue?Thank youRegardsGhiom Viguie
