Connect Issue between and Xplane 10.42

Recommended Posts

I had an Windows 10 OS issue and ended up re-installing which removed all my installed programs. I installed using Pilot2ATC_1433_Upgrade.exe. The app come up but displays an error when trying to connect. It reads:


Problem connecting to SIM or loading Recognition Engine and Grammers.

Error: The underlying provider failed on Open.


Should I be installing the Demo first and re-registering? If so will the Key I have still work or will a new one need to be generated?


Thank you,

You will need to install the full trial version again as it has the database, which is what appears to be missing. Do Not Uninstall Anything.

Then install the over it in the normal manner. 

 You should now be able to run normally.  If you get any registration errors, drop me a note and I can help you resolve it, but you should be OK.
