It occasionally happens when your pc crashes and you log in again before your original login has timed out, if you're worried your account has been stolen, just change your account password.
I got thrown out of the server after I played for a couple of minutes today with that reason. Then when I tried to reconnect it said that the VAC server couldn't be found.
hoping some of you guys can help me out here.
its saying my user id is been used ?
i read some other guys post on something similar but it wasnt my steam id it said was in use and im wondering if its the same solution as that above?
i got it to, have gotten it a few times, i have never noticed that my password has been stolen, i have only restarted steam and then it have worked mostly of the times
