My game doesn't start after the launcher work properly: when I launch the game it look as it'll go as usual with initial Mojang word on white board with the loadbar increasing but then it freeze and the game doesn't respond yet. it can stay in this state for several minutes, when i've tried to close it a warning windows appear every time 'java (TM) PLATFORM se BINARY IS NOT RESPONDING'.  I've tried to uninstall-install minecraft several time, even tried to do the same with java but nothing works.
