When only the demo mode is accessible or it's asking you to pay again, this means that you're logging in with an account that doesn't contain a Minecraft profile/username or a copy of the game. please visit https://help.minecraft.net/hc/en-us/articles/360029643892-Can-only-play-Minecraft-demo-Java-Edition- … for possible solutions.
