Fsx not loading after navdata install

used the navdata manager to install the fms data into my payware aircraft and fsx steam has failed to start, i uninstalled everything and rebuilt the sim without the navdata and still wont load, now my fsx steam is dead, its affected the Kernalbase.dll, NVcamera.dll and NTdll.dll, tried to fix everything and still nothing, ran a ccleaner, windows system checks, everything ran fine until i paid for the subscription …need help or its a full fresh reinstall of Windows 10, great stuff…

Hi…,

Welcome.

I don’t see how copying navdata to FSX Addons can affect FSX Steam start-up. I suspect something else at play on your system.

Try returning to an earlier Windows Restore point.

Cheers
