aerosoft france 2 problems,

Hi , i falt i'd asked here since u are all very smart =]

i have problems with france 2, iv installed it alll etc, but the airports are really bad , it looks like flat terrian , with aircrafts on it, the airports effected with this are , charles de gul, and biarritz, toulouse works fine, when i was installing it asked me if i wanted to replace a asil.dll or something i clicked yes, could this be the problem thats making it not work?, iv also tryed reinstalling, no effect
