Half-Life

[newone]

when I try to connect to a server, it say "Your CD-Key cannot be use on Valve system". This happens when I update Half-Life to 1.1.1.0. Know whats wrong ?

Do you have a legit (bought) copy of half-life?

[newone]

yes

I would try reinstalling Half-Life and any mods if all else fails. Maybe send an email to valve, or calling tech. support even. I believe if your cd-key was leaked out on the Internet--as well as some other situations--they'll "turn-off" your cd-key.

Someone may've used a key generator and unfortunately for you, generated your very own serial.. I agree that you should contact valve and they'll probably help you out.
