Hi there, quick question - in LFS' Options > Controls > Axes / FF, is the "Force Feedback" set to "yes"?
If so, is the "Force Strength" (same screen in Options > Controls) set to value higher than "0"?
(FYI, if FF is set to "yes" you can adjust the value using the keys "," and ".".
If the above above isn't working let us know - and we'll see what else might be wrong...
