Missing Projects

Alright so I am using FCPX version 10.3.3 and I decided to transfer a majority of my projects from FCPX to an external hard rive because I was running out of space quickly. I clicked on my library and then opened the "Reveal in Finder" button. After doing so, I dragged the projects I wanted to move onto my desktop, but after doing that all of a sudden when I opened FCPX up all my projects either have black screens over every clip, or they all say missing files. So the question is did I accidentally move some files that may have corrupted fcpx? or did I permanently lose all of my projects. How can i fix this quickly? I have already tried using Time machine to restore to a previous time before i messed everything up. I have also tried moving the files back but dont know where they belong.

**Side note** When I open up finder and click on my user and go to the folder labeled "Movies" all my projects are called CurrentVersion.fcpevent. Did I accidentally move these files or what?
