I have spent about 2 hours re-doing this level. Once I have activated switches 6 and 5, I then go on and try to activate switch 9 and it won't even give me the chance to do this and progress further. I ended up deleting the episode and re-downloading it because of this problem.
I also have a glitch where I open up the engine instructions and it won't allow me to move once I go out of them and this is also making me have to re-load the level.
Please can you guys fix this ASAP!!!
