im new to this forum, so i hope im writting in the right thread.
i just got into medium format film photography and got a hasselblad 2000 fcm, and it seems to work fine except for two main parts. first, the shutter does not retract when i take of the back. is that something i should be worried about? or was that just a feature to protect the shutter curtain?
second, after i took a shot, the crank arm to advance the film wont turn, except if press the red button. can anyone help me to fix that?

your help would be much apreciated!
