my flight simulator deluxe edition does not like my windows 8.1 . I have a problem getting the flight sim to open, and only after several yes several attempts will it work, What can I do??
A bad flight log will prevent the Sim to open but since yours does open occasionally ??? .
The cure for that is to delete the log file and fSX will build a new one.
Some members have tried this fix.
Without knowing your computer specs I can just guess that either you don't have enough ram or your h/d is near full.
