Not able to open socket manager

So I am making a baseball game, and I wanted to start with the pitching machine. Everything was going great and I even made the sockets. I was using a video tutorial for how to make a turret and was just going to turn that into a pitching machine. However when I got the the get socket transform to spawn the ball the sockets weren’t there. I went back to check for the, and they’re gone as well as the socket manager which isn’t showing up in the window drop down. Any help please, this is for a school project so I need it to work.
