Having some problems with Steam. Really annoying! All of my games that are in need of an update are not installing the update. When ever I click the resume update button, nothing happens. When I move a game to the top priority spot, it says it is starting a download but then it goes back to its original state. Not downloading. This also exists with downloading new games too. When ever I go to install it says this: "An error occurred while installing *insert game name here* (unknown error) Anybody know what the problem is?
