I sometimes have a similar problem with my CSL Base. From time to time I loose the whole feeling when I return to track after adjusting car settings.
For me it was some kind of driver problem. I reinstalled ("repaired") the driver and all is back to normal.
After testing all possibilities of what could be the reason of this problem and I am like 95% sure its something in R3E and not anything hardware or driver related. I hope the devs can get behind this because its really worsening the experience of this truly great game...
If I have my clubsport v1 turned on when I start raceroom it shows n on the readout and the force feedback shakes the wheel.. I have to turn it off and then back on again
