how do i remove a key on a computer that i dont use anymore so i can put it on the computer i do use?
i dont want to remove soldat from the other computer because my little brother still plays it, but i dont want my key to get banned if we both use it and jump in the same room.

You won't get banned from a server. I use my key on three computers of mine, and they even LAN fine. Don't worry about it.

Yes, I will tentatively say that this is a situation where it is alright for you to use the one key on those two computers

oh ok cool :) i was just worried about my key. thanks for the help :)
