everyone making it to level 45 (no matter how) is brilliant in my book. thank you for the kind words and your time.
the hint in level 45 has a bit of an attitude and makes you wait - but it is there ;-)
to be honest, the puzzle type you seem to have problems with is a 100 times easier with the right outside knowledge (which is the binary numbers system in this case) and I always felt a bit uneasy to include it because of that - so you can totally blame the game.
