Does your .cfg file look like this?
EnableRemainFuel=true
coordButtFuel = 25,175,20,6
coordButtLogoFuel = 93,22,20,20
# Display icon fule when remain resLap lap in fuel
resLaps = 2
If it says "false", change it to "true".
Are you running other insim apps at the same time as lfsrelax? I tried to run that Setupgrid app to download setups while in multiplayer, but it messed up my lfsrelax when I tried to use it. So having another insim app running might be the problem. I don't know.
