Cant use D button ...

Hey guys,
I got a problem using D button in Cross Fire so im forced to use F button,my D button works great outside Cross Fire but it wont work in it,any suggestions?

Check your settings in CrossFire.
And press thanks

Change your system's keyboard layout to English and it should work. Under no condition switch it back during the game or before the game (the system keyboard must be English). Or just use a keyboard layout that doesn't have alternative "d" keys (e.g. my one has "đ" and I therefore can't use it - you have the same one).
