In that case the film has already been fully rewound into the canister.
I've never encountered a lever that would not lift - it is just inserted into the spool of the film canister about 1/2 inch. There should be no resistance unless the canister itself is somehow twisted in its receiver - perhaps the bottom of the film spool in the canister was not properly seated in the slot. Can you work the crank upward at all?
Small bit of force with a flat object under the black disc? I know it isn't easy to know how much force to apply for fear of breaking the assembly.
There is a small, flat, hook-shaped catch just under the leading edge of the film door that engages the keeper on the inside edge of the door. The crank shaft lifts that catch to open the door when fully extended.
Looking at my MESuper. the crank should lift FREELY about 3/8 inch, where it engages the keeper assembly. Then a gentle pull of another 1/8 inch releases the door. There should be some spring resistance on the crank at the second step. If you can get the crank up to the point of releasing the catch, gently moving the edge of the door downward while gently lifting the edge of the door to "help" disengage the catch might work.
At this point (if you get here) some "assistance" on the leading edge of the door might be necessary to pop the door open.
