Can't use console.

Well, I’ve been playing around with some buddies in the Beta, using some cool addons. But the console commands regarding some of the addons are not available to me.
Why you ask? It’s because my developer console is behaving very strangely. It doesn’t appear in the main menu, no matter what I do.
And when I’m in-game, I have the console in the background of the pause menu, fully functional it seems, but I can’t interact with it whatsoever.

I’ve tried messing around with the options relating to it, and did a reinstall as well. Google’d around, no results.

So, I’m posting here, hoping for someone to have a possible solution.
