Ok so basically I decided to get MC back and after doing some requesting with Agents, They gave me a link to a launcher. I installed it, and then logged in. But after Logging in I keep getting the same error when Re-opening my Launcher:

                                                              Whoops!
{*}An Unexpected Issue occured; we are sorry for the inconvinience. Please try Restarting Your Launcher. If that Does Not Resolve the Issue, Please Log a Bug Report  +HERE
