[EN] Cs 1.6 problem

Hello everyone, I use to play Counter-Strike 1.6, and I've decided to start playing again. But now, when I start Cs1.6 (Steam and NoSteam) the game interface does not show any letters. [Only registered and activated users can see links. Click Here To Register...] What could be the reason for this to happen? I dont think that my drivers are out-of date, all of my other games are not working. Anyway, any help would be appreciated.

Thanks,
