Ok so since im not getting a reply from anyone on quake live forums i guess ill ask here.

So my game has been working fine when i boot it up, but recently it has been saying this thing that says "the underlying connection was closed: the connection was closed unexpectedly" and i looked at other forums there and they said something to do with cmd. The thing with me is, when i comes to stuff like that i have little to no knowledge at all.
So at first i tried to launch with and without firewall, same problem occurred wtf. So next i tried to uninstall the game and try to reinstall it. After reinstalling it the same problem occurred once again, so me being the retard i am when it comes to figuring out how to work games decided to uninstall the game once again, so now whenever i start the download it says "Installer integrity has failed. Common causes include incomplete download and damaged media. Contact the installer's author to obtain a new copy." So at this point i just gave up all hope and decided to look at the forums, and i still dont know what to do.

pls help :c ill give you a cookie
