Warning on using Unbind and Unbindall commands

Using these commands could result in problems related with controls such as movement, shooting, etc. Do not use these commands on pre-assigned default keys such as WASD, space, etc!

If you have accidently done so, your only chances of fixing this is to restore the config.cfg file located in: "Steam/SteamApps/common/left 4 dead 2/left4dead2/cfg/" to its original version. This may be done by restoring your computer, or the file to an earlier windows restore point. You could also ask one of your friends to send the file to you so that you could replace it.
