1.6.4 Never Loads, No Apparent Reason

[PotatoSamurai]

Perhaps related to using Task Manager to kill MC after a lag spike. This has happened before, but I don't remember how I resolved it.

Attempted solutions:

Updating from 953 to 965

Re-updating LWJGL

Installing https://bitbucket.org/luacs1998/forgelibrarydownloads/downloads/fmllibs16.zip

Deleting 1.6.4 versions, running game in 1.6.4, reinstalling

Excluding .minecraft from Microsoft Security Essentials

Restarting computer

Deleting /config

Restoring previous version using Windows Restore
