If you have the steam version, it should update automatically. Not sure exactly how the Humble Store standalone version works, but if it doesn't have an installer/update client, you may need to download it directly from the store after logging in. If you have neither, you do not have an official version of the game, and it is unlikely you will find any assistance here in that regard.
