If you are having trouble putting a lens on stop what you are doing!
Both the lens and the body must be cocked.
See if the lens is jammed and correct it:
Make sure that the body is cocked. Crank the film advanced. If the body is jammed:

Wind the camera. If there is a back on the camera, and it shows a white dot near the frame counter, remove it, then wind.

Note that Hasselblads don't have "instant return" mirrors like typical 35mm cameras. When you release the shutter the mirror stays up until the camera is wound. The body must be wound, and the lens cocked before mounting a lens.

First I would tip the shutter button. Does it fire? The mirror was pre-released then. Does it nothing? Check if the dark slide is in the magazine and if so, pull it out. Try again to fire. If it still does not fire, try to wind it. If this does not work something may be seriously wrong...

It's broken. Send to me and I'll generously pay for shipping.
Oh, OK...you will pay for shipping AND repair it too? Now that's a great deal!!
Welcome to APUG
Do you have an instruction manual? The 501CM has a pre-release (mirror lock up) function which allows you to exercise part of the exposure sequence and then release the shutter later with a cable release to minimize vibrations. The button is located just beneath the film advance knob. If the camera has been pre-released but hasn't completed the cycle, everything will be locked up. You can't advance film or mount a lens. You'll have to figure out a way to complete the cycle, then you can perform the necessary preparations to the body and lens to allow them to be re-coupled. Have you tried using a cable release or tripping the shutter button to finish the cycle?
It is difficult to analyze the problem not having the camera in hand but it does sound like the camera is in the middle of an exposure cycle initiated by the pre-release button and has not completed its cycle.
Good Luck!!
PS. There are troubleshooting hints in the last pages of the manual.

Was the camera presented as being in working condition?
If you're in the U.S. David Odess is one of the more popular Hasselblad specialists, out west there is a good Hasselblad specialist at Samy's camera in L.A.

I would like a bit more information - perhaps it will provide a clue. At the moment I can't tell if it's a case of unmounting an uncocked body/lens or some sort of pre-release state.
First, remove the film magazine completely to simplify things.
Q1: Are the rear baffles open or closed? If open, that would suggest a pre-release state. If closed, that would suggest an uncocked body.
Next, press the shutter release.
Q2: Does the release press in or not move at all?
Next, Try to wind the body.
Q3: Does the wind lever move? If so, that should cook the body and bring the mirror down.
Next, push up on the pre-release lever.
Q4: Does that open the rear baffles? If so, you may be able to press the shutter release?
Finally...
Q5: looking at the bottom of the lens mount on the body, at the round end of the cocking shaft which contacts the lens, does the "blade" of the shaft point at the red dot or not? If it points to the red dot, the body is cocked.
Knowing the answers to these will at least give us an idea of what state your camera body is in. Don't despair, I've been using Hasselblads for over 20 years and have never had a single jam or other issue.

Seems this procedure is successful in a great many Hasselblad jams:

Yes, from your answers I agree with the previous poster that your camera is stuck in a pre-release state. Unfortunately, this is something I am not familiar with repairing.
Just out of curiosity, I googled "Hasselblad stuck in pre-release" and found mixed results in terms of solving it by oneself. The one successful result was in this thread:
http://photo.net/medium-format-photography-forum/00Wt9e
basically suggesting to gently use a tool to wiggle the cocking shaft. That person had a mounted lens, so he had to access the shaft from the rear. However, you mention that you cocked it manually already, so I personally don't think there's anything left to try.
Thinking about this some more - the fact that the release presses in and nothing happens, nor does a cable release work, I think the problem is in the actual tripping action, not an issue with cocking or other mechanisms being locked up.
I would say get it serviced and then you'll have a known good reliable camera.

Since you say the pre-release looks like it's stuck in its up position, it might be the cause. Maybe there is some packing material or other foreign "stuff" locking it. It might work to try jiggling it either by hand or a small screw driver to see if it will return.
Otherwise, a trip to the camera doctor is probably in order. Turning the cocking shaft as in the link might work too, but I'd probably not want to risk it.
In addition to the other repair places, Zack's camera in Providence RI is good too, and he's an APUG sponsor.
(assuming you're in North America).

Is the shutter release set to O or T ?
That switch doesn't exist on the newer 501 series; neither does the body-cocked indicator.
Only time I've had 500 C/M's jam was when using the pre-release button. Consequently, I don't use that "feature". Time for a service. L
