I just bought Minecraft java edition then I made an account after buying it then I open the Minecraft Launcher and it says "play demo" when I just bought it 10 minutes ago. I just logged out and logged back in and now instead of saying "buy Minecraft" is days "download" and when I do it it just says repair and removes so I repaired it and it did nothing then u removed the launcher and reinstalled it and they didn't do anything either it still says in the launcher "play demo"
