FSX-MS fsx - trackir / ezdok problem

[jaguara5 1]

When fsx's main screen is loaded, I get a message ''ezca for fsx has stopped working'' (twice), and when I close the program, the right trackir 5 sensor light goes out and neither ezdok or trackir are working.

Same thing happens, if I manually run ezca after fsx is loaded. trackir and fsx are running as administrators. My fsx install is stable, until now everything was running fine (for years), few times trackrir wouldn't load properly but restarting the sim would solve the problem. I have not problem in other sims (dcs, bms). Also, until now, trackir would load , only if I had selected to run fsx as administrator.

Also, if I disable temporary ezdok , through the respective xml. file, trackir won't load (the right sensor light is remaining off).

My system : W10 64 bit, gtx 1070, 16 gb ram, trackir, fsx, ezdok, asn, rex4, pmdg 737ngx, few addons.

Any help is appreciated.

Thanks
