Hi wael,,
I am not from Laminar Research, just a flight simmer from downunder.
More detail is required so that those with a greater knowledge base than me can attempt to try and answer or solve your problem.
What version of X-Plane are you trying to run? Is it the official and current version of X-Plane from Laminar Research or the independent 3rd party hybrid version called steam? Steam is not the same as the Laminar Research version. Steam does not mix with the official version from Laminar. Laminar does not market steam.
If you are running steam you should post your question on a steam forum. This site is not a steam forum site although some steam flight simmers do get an answer.
What operating system are you running?
What are the full specifications of your system? Is it a PC or a Laptop?
Finally attach the log.txt file as well. This file is generated immediately after you shut down or your system crashes. It can be found in the "root" directory of X-Plane
Thanks
Glenn
