the #hash tag thing is something to do with the language .xml files I think...
try changing language inside of extras > options.
as for 3d card settings: right click somewhere on your desktop > graphic properties.
something like attachment 1 should pop up... click 3D settings button...
another box will popup... enable settings I mentioned earlier.
as for the control interface; it is done via the interfaces tab in which you create buttons/commands in which you can use to decide what actions your character can perform/execute in game. For the interface to work it has be assigned to a character on the scene - i.e current character you are controlling.
