having trouble getting hori fs3 working with pc. HALP!

Hi all I been searching the nets for hours on end and I cant find anything that seems to help. I Know the hrap3 and the vfhg work out the box but until funds let me I'm stuck with this atm. I plug the stick into the usb and my computer recognised(sp?) it but under the game control menu thing I couldnt get it to see that i was pressing any buttons or anything. I found a driver that said it should make it work I think it was of srk but I couldn't get that to work kept saying it couldnt load hardware because of something being corrupt with the driver. Any help would be input would be greatly apriciated.
