I keep having the problem that the command button and a few others won't work. And now I no why: after every ... - well, I don't know what's causing it actually - the commands which I bound to the numpad are getting rebound to the same key and so none work...

I'm pretty much at the beginning of the game where I should get some Fireflies(?) from a huge tree.
Before the cut scene where she tells him to get a Firefly, the buttons work. Afterwards they are reset!?
When going back to the main menu to view the controlls you can see that they got rebound...

Anyone have a solution for this very peculiar problem?
