Followed your advise re antivirus but there is not difference. I have a dedicated SSD for the simulator and normally an antivirus exception is being maintained. Did switch it totally off for testing (MS Defender). Can you further clarify, " Make sure the feelThere folders with the game are bit locked/protected"? Not exactly sure what you mean... My feeltThere folder properties tab indicates: Attributes - Read-only (Only applies to files in folder)
The e170 configuration settings file indicates:
;0 - pounds
;1 - kilogramms
I note the spelling error in respect of "kilograms" but presume this has no impact as the line fuelUseKg=1 and thus applied.
The relevent tab in the configurator keeps switching back to Imperial (LBS).
Sorry to bother you with this but would like to have it sorted out if possible.
