http://pastebin.com/V9DVHbws Here is my crash log. I'm very new to this so I have no idea what to make of any of it. The launcher works fine and everything runs great until about 30 seconds to about 5 minutes of being in the world, it just closes out.
 
(The requested operation cannot be performed on a file with a user-mapped section open)
What does this even mean? First time I have seen it. Hope somebody knows.

Description: Exception in server tick loop
Can't remember the solution to this one. Is it only on one world or all worlds? Does it always crash?

How much RAM are you running with? The java parameters are set to 2GB (where do all those parameters even come from?). The crash report says that there is less then that.

Windows version 7 64bit. looks alright here.
Java version 1.7.0_55. looks good there.
