i can run anything from the technic launcher to the page where you choose singleplayer or multiplayer just fine but when i hit create world in singleplayer it generates the world saves loads the chunks, and saves the chunks, but when im almost in, it closes minecraft and brings up the technic launcher. i have tried deleting the tehnic launcher and file, deleting only the file, changing my ram from 1 to 7 and back to 1, and i dont know what to do.
