So, i downloaded a few mods and at first minecraft wouldn't let me open any saves, it'd act like it was working and then take me back to the title screen.
After rage-quitting and giving up on that i closed the game, reopened it and changed it so it ran the latest version of the game. The launcher said that the game was already running, so i restarted my PC. The launcher still said it was running so i tried to delete my minecraft folders and reinstall it but-
-My PC won't let me edit any of the folders because the game is 'already running.'
THEN i redownloaded the minecraft set-up launcher thing and tried to get that to repair the game.
I then tried to get that to delete the game.
It said it didnt work but the minecraft set up thingy said i could download the game again so i decided to do that.
Now the launcher won't open at all.
