The problem with the gamepad. (Gears of War)

Wanted to write to technical errors, but not seen the problem...mmm...enough hardware evil =)
So: when playing a gamepad left stick somehow inverted on the y axis. i.e. when you press forward, the character goes back, and Vice versa. The same thing in menus - I press up and it down =\ I Tried to use the Profiler program that comes with drivers...didn't help.
You can, of course, watch the left stick, and walk right...but it's annoying >_<
Device - Logitech Dual Action.
Oh, and don't advise to play on the keypad, the mouse) I Have a rule - if the game can be played on the gamepad - you have to play on it ^_^
