I ran into this also when i tried to use windows 7 ,found no fix ,or plug in that would fix the force feedback issues.
I love my Sidewinder stick's so much i did just as you for mentioned.
No sapport at all for them anymore at all ,damn shame to ,one of the best force feedback sticks ever for the cost.
Whats your problem with the sticks? Sidewinder support is built in Windows 7. Are you missing force feedback?
Really? i have the cd for the stick and it never worked with windows 7. Tell me how to fix this?
