Okay, so I had a Mojang account. When I went onto Minecraft Launcher my account info was there. So I clicked login. It said Login Failed and there were two options 'try again' and 'play offline'. Is this because I don't have the latest version of the game? I didn't know for sure so I made a new Mojang account and got onto the launcher and typed it in. Then it said User Not Premium and had two options 'try again' and 'buy game'. I don't want to buy the game again and I don't know what to do.
Hi,
It seems that you somehow found your way to a very old version of the Minecraft launcher.
Please download the latest Minecraft launcher from here: https://minecraft.net/download
