I own Minecraft and have already bought it....still tells me to buy it from the Launcher. i have tried re downloading MC launcher but it still doesnt work.....surprisingly lunar client works with the account but lunar client doesnt support bedrock edition.....i have tried signing out and signing back in as well as trying to download the windows 7/8 launcher
