When I looked this problem up online, the problem people had was that, when they tried to connect, MC would attempt for a while, and then crash. For me, however, when I pressed multiplayer the first time, it allowed me to add a server. Once a tried to connect, MC instantly crashed. From then on, just clicking the multiplayer button from the main menu instantly crashes the program. I can't find any documentation online. Any ideas?
