Alright, I'm finally getting around to configuring my adaptor for my pc to work with my ddr pads, yet I've installed the driver and nothing is happening. Any suggestions on what to do?

1) Some adaptors require you to hold up, start, and select for 3-5 seconds after you plug it and the pads in to get them to work.

2) Go to the configure input option in Stepmania. You need to configure the pads to the different keys (up, down, left, right, start, back)
