Issue: Settings/ Profile won't get saved or get lost

Hi!

First I hope I'm in the correct spot with my issue. 

I'm playing assetto corsa in pc and added some rumble motors via arduino. Everything is installed and working, just after each restart of the pc the settings are gone.  The arduino and motors are found and recognized, just the effects are all "off" and set back to original. 

Can't find a "save" button or something?! 

Greets!
