The game is crashing when i try to enter my save!

so, what?

can i fix that or not?

Please also attach the launcher log (.minecraft/launcher_log.txt) here.

ok i find the problem, i was change the alex skin with my skin, because i was offline, so the game is crashed when i was do that, but when i was do that with the older version the game was never crash, why?

now i create a resource pack include my skin.
