I just bought Cs: SOurce and thot if i created a new steam account seeing i have cs 1.6 installed it wood let me play both games. Now I cant so what do i do?
If I understand you correctly, you created a new Steam account when you installed CS:S right? Under the Games menu in Steam, there is an option to "Activate a Product on Steam." That is what you should have done when you installed CS:S, or simply used the account you already have when it was installed.
If I were you, I would check into contacting Valve and asking them if they could transfer your cd-keys to the same account. Try sending them an email with your steam account names, the emails on both accounts, where you bought both games, when you installed both games, explaining what happened and what you would like them to do(i.e. terminate one of the accounts and release the cd-key so you can play both games on the same account). Make sure NOT to send them a copy of your cd-key, or passwords for your accounts in any emails.
You may have to send in your CS:S cd-key to get a replacement, but I'm not sure. If you do have to get it reset, you can find out how to do that
here.
Be as specific as possible in your communications. The worst thing you can do is to sound sketchy, they'll deny you flat thinking you're just trying to snag someone else's keys.
