Hi numan,
I am not from Laminar Research just a flight simmer from down under.
Because the current version of X-Plane is now XP11 there will never be any updates for XP10 but it is still supported. The last version being XP10.52.
Normally when files are missing the advice given is to run the valid X-Plane installer file. In doing so your X-Plane directories will be checked for missing files and also replace any files that may be corrupted.
Good luck
Glenn
