There are a couple of possibilities.

First, double check that there isn't something like a neck-strap blocking its further travel.

If that isn't the problem, it may be that the camera thinks that the film has already been wound and the shutter cocked. That means that there is a problem with the interlocks.

Is the dark slide still in the film back?
