One of the changes made in the 1.0.3 patch was to improve support for the Momo Force wheels - so your best bet is to update to that version (and be running the latest version of 10.2, which is a requirement for force feedback).
If you're having a problem after updating, contact support at f1support AT feral.co.uk and they'll pass it on to us to take a look.
