Hatsan Flashpup magazine reassembly

Super embarassing to admit, but I have 2 that I can not get back together! Are there any videos or links that could help me? Thanks in advance!
Most magazines are similar. The spring should only be able to go in one way. Then start winding the center wheel. The wheel will hit a stop , you then need to lift the wheel over the stop. Then put the cover back on. Now you should be able to wind it the rest of the way
