Are you getting any error messages when you try to get in or it just crashes? Do you get the "failed to connect to map server" message or anything? Maybe try uninstalling and deleting your FH folder and then reinstalling your game. Just back up all your important files like presets, maps, and screenshots though. It's possible you messed up some of the game's default files some where along the line and that's whats causing it. Good luck and let us know how things work out.
