I tried to play minecraft a while ago, but the launcher didn`t even open. It said:

FATAL ERROR: net.minecraft.bootstrap.FatalBootstrapError: Unable to un-lzma: LZMA.LzmaException: LZMA : Data Error
at net.minecraft.bootstrap.Bootstrap.unpack(
at net.minecraft.bootstrap.Bootstrap.execute(
at net.minecraft.bootstrap.Bootstrap.main(

Please fix the error and restart.

How can I fix this? I have mc 1.6.2, with no mods, I didn`t use world editing programs at the time I was away from mc, and 1.6.2 has worked with no notable bugs for me, And I also tried to launch minecraft offline... I have no idea how I can fix this.

Help me, please!
