there is this problem with the Minecraft client not allowing me to access the full version.  I have owned Minecraft for 10+ years and this has never happened.  It's already a Mojang account, and not migrated.  I have reinstalled, logged, signed out then back in, tried other accounts, and different versions all the way back to 1.10, and still only Demo available.  What the hell is going on? I have worlds I want to play on, and last week it was working completely fine.  I just don't understand why I would get the demo instead, my account clearly says I bought it years ago.
