Key strokes don't work

Yesterday I played and everything was fine.
Today, I log in and the “Attack” key or any other keys on the right hud (“stop”, “hold”) don’t work, I press “A” and nothing happens.

The only thing I can think of that happened in between was the client beta update after yesterday’s game…

if anyone encounters as well.
I just did “Restore Defaults” in the options menu and it works…

You can go to the test server to see if you still have this problem
