Difficulty configuring XBox 360 Controller with ZDoom

[jute]

I just got an XBox 360 controller to use with ZDoom, but am having significant trouble configuring the buttons. ZDoom doesn't seem to recognize the d-pad, the X, B, and A buttons, the non-trigger shoulder buttons, or the start button. I have Microsoft's XBox 360 software installed. I have no experience with one of these controllers and am not sure what to do. Any help would be appreciated.

Did you enable xinput controllers?

Options>Joystick Options
Enable controller support and xinput controller support, make sure directinput and playstation 2 controller support is disabled.

I can confirm functionality with ZDOOM 2.5.0 (r2508)
