I think I figured out what was going on. When I replaced the config files I didn't delete them myself, I dragged them over and it asked me if I wanted to replace or something (I didn't really read it). I went in again and deleted the config files from every client and the server except for one and then copied the remaining files into all the ones that I deleted the files from. After running the server, to my satisfaction, I found this worked and now everyone can connect.
