I bought half-life when it first came out and now recently playing half-life. I have half-life loaded on two computers with the same cd-key playing on the internet. The problem I am having is I can't get one of the computers in. I get the cd-key in use message. I am NOT asking for a cd-key. I just want to know if there's a way I can use a setting in my SMC Router to trick the server thinking it's the same computer. If not, then I am willing to buy half-life, but was wondering where is the cheapest place to get it.
