Basically i use twitch to play modpacks and i press play and it shows my main minecraft launcher not twitch's one made for the pack so i manually go in task manager and then close it down fully then i open again and it works!  but then i press play in minecraft it says i'm already  playing the game...... but i'm not so i go to close down the hidden java task but its not there! it was in the launcher so i close both of the java tasks i see and when i do it says on the launcher your game crashed but it was never showing anything then i press play it says same error of "you already playing" but i'm not and if i press continue nothing shows :| please help  (edit: is it just me if so how do i fix it? edit2: it also happens on normal minecraft)
