Keyboard in BF2

[thecremeegg]

I've recently installed Windows XP 64 bit edition. Everything runs fine except BF2 - it wont register my "s" key so i cant walk backwards, slow down etc

I know its not the keyboard because it works in word and firefox etc, plus I've tried my sister KB and it still doesnt work!!
I have the latest patch......any ideas?

Thanks

Tom
