I updated to last version but problem wasn't fix. I performed clean installation of FSX and now I has working GSX. I don't know what caused problem maybe some file was corrupted? Thank you by the way.
I can't say which exact file in FSX was missing/corrupted but, of course, since it was fixed by reinstalling FSX, the only sure thing that it was an FSX problem that didn't had anything to do with GSX, that was just affected by it.
Maybe the Simconnect libraries or the VC++ runtime libraries, which are required by all 3rd party addon modules.
