Help! Always Crashing upon Joining!

[AwesomeAntlo]

So me and my brother were having some fun playing big dig on a LAN server. I am running a Macbook Air, and he is running a Windows 8 Dell. He was hosting the lan server. I didn't know that the computer was close to dying, and it went blank because it had died. I plugged it in, then opened big dig and tried to rejoin. It wouldn't work no matter how many times I tried!

So Anyone have any way of fixing this?
