Pentax 67 - ASHAI Metered Prism

Hi All,
I recently got, what I consider, to be an absolute mint Pentax 67, in great condition, with a metered prism. I checked it out before buying, and everything worked beautifully. I was putting the the first few rolls of 120 through it. I removed the prism to blow a speck of dust from the focusing screen, and when I returned the prism to the camera, the meter was no longer working. I'm quite perplexed by this. I checked the contacts between the camera body and prism, and ensured it was snapped into place properly. I have an external meter I can use. However, I was very pleased at not needing it due to the internal meter working. Is there any kind of trick or procedure for getting the internal meter working, that I might be missing. This is my first time using a Pentax 67, and I find it hard to believe that after removing and replacing the prism the meter now no longer works.
 
OK found the answer on YouTube -
I wasn't aware that there is an order by which one must removed the lens / prism. Furthermore, removing the prism while the lens is still attached can damage the metering chain on the body of the camera.
