Every server I try to log into just causes a window to pop up saying that my Steam account was being used on another computer and will not let me play. I called my friend, whose computer I logged into Steam on about 3 days ago, and had him make sure I wasn't still logged on. I wasn't. So I tried connecting to a server on TF2 and L4D, and surprise, surprise, no problems. Is this a problem that other people have had or is it something wrong with the installer? EDIT: I've tried uninstalling and reinstalling the game several times, but that hasn't worked either.
I actually decided to start playing again today only to find out that I get the same message. All other games obviously work like they should so I am curious as to what the cause for this message was.
It happened to me when I logged on to my other computer, if you have used another computer for steam, try to log on to that computer and then log off again.
