The server didn't crash, I think I accidentally pressed my power button, so my computer went to sleep mode. lol. I restarted it just now to clear up any lag problems.

Also, how in hell do you run the server thing?
It comes up as an unknown file.
If you get hMod, all the files are ready for you. If you don't, the .exe runs if you click it, but lags like crap. If you want to run the normal minecraft_server.jar, make a .bat file in the same place as the .jar file that says just this:
java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
if java isn't a known command, google how to set java to a PATH variable.
