You didn't give any information whatsoever. Like what keyboard you use, possible settings you made, any keyboard software you may have installed, keyboard layout, location settings etc. You also didn't post any kind of log.
plazma did post his log, however from the log it seems the client was not installed properly, not to mention he too didn't specify the keyboard or location settings, keyboard layout etc.
