Problem with setting PS3 controller control settings on PC version

I own the PC version of NFS:MW (2012).

I own a usb PS3 controller.

I set my controls as such:

"accelerate" R2

"reverse" L2,

"brake" R1,

"handbrake" L1,

steering to the left thumb stick,

the camera to the right thumb stick,

the easy drive and menu scrolling to the dpad,

x for nitrous and accept,

o for cancel,

triangle for swap cars,

square for horn

start button pauses,

select advances the music to the next track,

home button brings up the autolog

Problem is, when I actually start the game, 

I cant accelerate, and my car is stuck in reverse

and the only button that works out of the whole configuration is pause and skipping the music

Another problem I saw

was when selecting the controller buttons, the game was registering those buttons, as the wrong buttons, triangle being o and so on and so forth..

I have no clue how to fix this problem as I've tried it with 2 different usb controllers with the same outcome...
