Episode IV - 'Death Star Escape'. Bug doesn't allow to finish the game.
I have a problem in 'Death Star Escape' (Episode IV) level. It's on the begining of the level when you have to take a vehicle to press 5 square buttons on the ground. They are green outside and red inside (changing into green after driving over it), but for me the buttons are black outside, and as I drive over them red part changes into green, but nothing happens ;/ Here's a ss: http://i.imgur.com/EctRQL3.jpg
