This one felt pretty obvious where the correct path was, it was just a matter of getting there efficiently. Took me a few tries, but eventually made it work. Just an OK level, IMO.
This level really gave me a hard time. It just wouldn't load and open. But after I finally managed 2 open it - thanks to qllmus and Niels - I took 2 tries. Guys, ur really great, thanks for helping me getting it opened ! :) Edit: yes, it said some kind of error and to turn to administrator ...
