Ok I did a search in my regedit and took all keys witch the key value "keyboard" and got 30 keys, then I went to a new account and took all keys there and got 26 keys, while 5 of them I could not import to my main acc, but it didn't help.
So there might not be any problem with the registry, but there might be something wrong with the keyboard layout, because if I change to, let say US the button works, but it types a different letter, if I then change to Finnish, the button stops working. But it might be because it use the same keyboard layout as my main does (Swedish) because it looks the same, so unless I get a way to replace it I think I'm stuck, if not anyone can think of something.
