Cheat Code command box window doesn't show up

Alright, so even when I use  “Ctrl + Shift + C” the Cheat command window doesn't show up. In build mode or any other time. Now it worked just fine before the last patch. I have tried everything. I disabled all my mods. I tried the repair option, I've tried uninstalling and reinstalling. The window still doesn't show up. So I'm stuck. Anyone got any ideas what might be going on?
