So i've had Civillization 5 for a while now and decided to try to play online, but i can't click the internet button. When i hover my mouse over it it says my files are not synchronized with the steam cloud or something like that. I have been playing it on another computer for a while now. (I have neve tested online before.)
Do i need to uninstall it on the other computer? If so, how do i uninstall a game from steam?
