If you have an FT that has a black plastic connector, once you pry it apart you have to whack it back together again. Take the liner out, get a hammer (preferably with a plastic head) and give it a pretty good hit. Make sure you have something hard on the inside of the shell to whack it into (anything that is as wide as the shell is so the black piece doesn't fall out again). If you break it, they've updated the connector so it's way easier to put back together.
