Console not opening for months now...

My console used to open with the `/~ key and after reinstalling my game it won't open anymore. I uninstalled and reinstalled several times, I searched online for a couple of answers...nothing works. I tried to bind the console to another key and it still won't work. The reason the console is important to me is that it's normally the only way for me to connect to multiplayer games, otherwise I always get a "failure to connect" message. So for about two months now I have not been able to play multiplayer at all due to this issue.



Is there a fix for it or anyone else had this issue before?
