OMG I NEED HELP. I downloaded all of the games and played all of them and was ready to play CS:S and when I clicked on it. IT GAVE ME AN ENGINE ERROR. It says "Client.dll Intil() in library client failed". What do I do? Is it safe to uninstall the game? Will it ask me for the Key again to install it again because (this is embarrassing) I was chewing on the paper (kinda a bad habit) and I though I was chewing the other side but it turned out that it was the side with the code on it. So now I have a broken CSS and half a CD-key. What do I do?
