    • I have the latest java and my Operating system is Windows 7.
    • Unconfirmed

      When I try to get on any singleplayer world the game crashes, it doesn't even try to load. It just gives me this:
      http://prntscr.com/4hlu68 .
      When I try to get on multiplayer, it doesn't connect to any server. When I try to join, it says there is no connection.

      How to recreate:
      1. Join minecraft.
      2. Get on singleplayer.
      3. Join a world.
      4. It crashed.

      I've tried some tips I got on other websites, for example I scanned for malware and turned off my firewalls and antiviruses to get on minecraft, and it didn't work. I tried to restore my pc to a week before, it didn't work.
      Anexed will be the crash reports. This is what the launcher says:

      ---- Minecraft Crash Report ----
      // You should try our sister game, Minceraft!
