why is your wasd realiased, maybe you have something in there breaking it.
the hud disappearing happens when an animation isnt triggered to bring it back. for example if you bring out your melee and the game never registered that you switched to your primary itll happen.
the obvious fix is to verify your game integrity, do an -autoconfig in your launch options, and then exec whatever weird cfg you have later and see if its breaking it.
i have the null movement script thing which is why they're realiased http://pastebin.com/ZAcj0TBx
ill try the autoconfig thing
edit: backed up & deleted my cfg folder and launched the game with -autoconfig, still broken
