The PS2 Controller is not designed for the PC so this must be where the problem lies. Have you tried buying a new PS2 to PC adapter? Does the analloge work?

But from the sounds of it there a software confllict somewhere, first of alll try using if theres anything that can be done from the controller menu in the windows control panel if not your only option may be to format your entire drive and then re-install.

Un-installing a game or drive usually leave files such as setting which wiill not be reset so the problem will still be there.

This seem to be a common problem with all ps2 to pc controls so its not gonna be easy to fix but can you try these ideas?:

1. Press Up+Start+Select and see if the down button starts working

2. Try using it at the same time as another button

Un-install the game and the controller drives and then DELETE the folders that remain for the drive and game then try re-installing
