The game doesn't recognize my keyboard!!!

So I can't move at all in the very first screen, either impossible to enter to the menu... but funny enough Shift+Tab works normal, also all Windows keys (Alt+F4, etc, etc, etc).

And this bug only happens when I install the game using Galaxy, even if I launch the game directly from its exe.
Gladly, standalone installer works as it should be, so, somehow, somebody, touched something and the Galaxy installation becomes corrupted.

Before someone complains, I tried everything I could think of before posting this, like:
install/reinstall;
changing keyboard port;
changing keyboards (all wired);
restarting PC and starting all over again;
installing other games through Galaxy to see if some of them trigger the same bug (none so far).

Just posting this here so you could be aware of this issue (I wonder if someone would try it on their own and replicate this bug, or this its one of the most bizarre bugs than only had to happened to me).

Not really a fan of opening a support ticket if I have to wait 1 week, or more, for an answer.

It's not completely unknown for installer and Galaxy builds to be different for no clear reason: it is, or was, the case with Arcanum, where the Galaxy-installed .exe was a different size and had compatibility problems the one from the installer didn't. At one point I had a ticket open for that on the Galaxy bug tracker, then eventually a staffer closed a load of old tickets because they were created some Galaxy versions ago, saying people should open new tickets if the problem persisted. Given that the bug obviously wasn't in the client itself, I was not motivated to do that.

I haven't looked at Braid, but if you compare file sizes or hashes for its .exe and and library files between Galaxy and installer versions, that might give you a clue about what's going on if it's a similar case.
