Hello Nick,
I've deleted the rolling cache but I'm having trouble finding the Microsoft.FlightSimulator file. My pathway is Local Disk(C:)/Users/wrenh/AppData/Local/Packages. What I can find in alphabetical order is; Microsoft.ECApp_8weky...., then Microsoft.GetHelp_8weky.....
Have I picked the right pathway? Microsoft.FlightSimulator should be in the middle of those two.
Regards
Rod
