So, I had a fully working R3E going, using my Logitech G27. Sometimes there are issues that either the steering or the pedals don't work, but you restart the computer and all is OK. This time, I noticed that I suddenly coulnd't race at all - both steering and pedals don't work. Weird. Then, it seems this is the behaviour ONLY when trying to race online. So I can do single user event, or leaderbord, but I can't race in any online game. And all of this is within the same running of the game. So, I can race a normal race, no issue. Try to race online; doesn't work. Go back to normal race (offline); still works. What ? I know there's lot of steering wheel support issues, but this one is a step beyond!
Have you tried checking your controller profile while trying to race online? maybe somehow Keyboard profile is active.
