Really? I have no problems using the latest logitech drivers, (5.01), with that wheel. Have you tried reinstalling the software? or maybe there is a fault with your wheels FFB??
Latest 5.02 drivers were a big improvement over 5.01 for my dfp, the .01s gave me some hassles with dropping FF totaly at the most in-opertune moments or games not picking the setup up at all, not had a prob since changing to .02s though and they let you switch those damned annoying sounds off in the test window, they also allow the game/sim you are using to adjust the wheel settings to suit the game/sim.
