every time I run minecraft itll come to the main menu and I can pick if I want to play online or solo. yet when I pick either and I generate the world it crashes and keeps telling me something about java. I have the latest verson of java and am running a windows 10 HP pavilion. its a duel core 2.4ghz with hd integrated graphs. I would really love your help with this issue or at lease a refund of the game. but I would love it to work as my younger brother loves the game and I'm trying to help him out by trying to fix this problem. I really love what you guys do and thank you for your service.
