ok so i was playing on a server then all the sudden its crashes and brings me to the launcher.

i close the game the start it up again... i click PLAY and it does what it usually does, but it doesnt show it loading usually theres a blue strip that shows its loading but its not there. I close the game AGAIN... then do the same thing still, nothing. i do it a couple more times then i clicked the launcher log and it said this
