Crash





Crashes are unexpected shut downs of Minecraft. When Minecraft crashes, it typically closes immediately, though it may show an error report marking the location of the exception which caused the crash. The most common cause of crashes are mods and preexisting bugs. Attempting to modify the files of Minecraft or individual worlds, even with advanced editors, can also cause crashes.

Crashes used to have an error report but that feature has been removed due to large amounts of mail inside Notch's Inbox.

Step 4: Save the file, but as a BATCH file.
