Ugh...I hate that crap Bads1. I have the same problem with my Interact Hammerhead controller. Their best PC controller ever and they don't plan on supporting it anytime soon. It sort of works with XP, but there is no button remapping, no vibration feedback, no extra features, etc.
I think many places are doing this because they think that you will go out a buy a new one from them. What I did was shoot off another nasty email to a customer service manager saying that I refuse to buy another one of their products ever again if they don't give proper support for their product. Why would I after all if they don't support their own products? I also said that I would also post on message boards and other places for people to avoid their products and about what lousy support they had. Try it and see what happens.
