DmC with PS2 Controller Problem

[Bude8]

Hi guys, I've started playing DmC and I'm having fun on the keyboard, but I'd like to use my PS2 controller with it. It worked with DMC3 and 4, so I was a bit puzzled as to why it didn't work here. I can plug it in, and press keys with it that perform actions, but the bindings are really weird,
Eg, Triangle = Jump
L1 = Start

Now whenever I go into options and gamepad keybinds, and rebind every key to my preference, I then press back and the keys automatically rebind themselves to the default. How can I sort this problem?
