So.... no one play Nancy Drew anymore? Just me? Sad....

Hey! I am playing the game and tried to find the envelope in locker 49 right at the beginning and it isn't there. So i started reading walk-throughs to see if i missed anything and i notice as well that coins are not where they say they should be....what am I missing?!...

I know the order but cannot get it done fast enough to finish before Bridget comes back

Whenever I try Nancy just says "Hmm".
