GTR EVOLUTON HELP.

Hey, got myself a copy of gtr evo the other week for something more "simmy" than ferrari challenge on the ps3, however the force feedback function doesn't seem to be working with my steering wheel, which is a logitech driving force gt, i have tried everything, changing the in game control/ffb settings, re-installing gtr, re-configuring the wheel and yet the steering has no ffb and feels like, well it doesnt have any feel at all, its just really light, if anyone out there can help me it will be massivley welcomed, cheers for reading.

Have you installed logitech drivers? Is the logitech profiler running in the background? And last but not least, is the unit plugged to the power outlet?
