xbox 360 controller won't rumble!

[caseyallenellis]

Hello there. I've read many of the threads on here talking about this issue. People have fixed their issue by choosing "Left/Right" under the rumble section. My problem is there is no Left or Right option on my menu! Under the "rumble" section the only options showing up are:

Constant
Square
Sine
Triangle
Sawtooth Up
Sawtooth Down

That's it. I can't figure out how to get my rumble to work.
Thanks for any help!

Rumble is currently slightly broken. The fix is pending.
You should be able to work around the problem by mapping the output TWICE with the "| OR" button.

The rumble button should then read something like "Constant | Constant"
