Yes, I am talking about the locking knob on the flash. Make sure the flash is pushed all the way into the shoe then turn the locking knob all the way up so it is tight to the flash and as far away from the camera as possible. Then try to remove. If you have tried to pull the flash off without the pin retracted it may be wedged against the slot and stuck in the down position. So a little wiggling might help but only with the knob all the way up.
It took me awhile but I eventually got my Metz 48 off and once I looked and understood how the little pin works I've not had a problem again.
