I just migrated my mojang account bought a long time ago back in like 2008-2010 and now it...

Greetings MineBoss2000,

Sorry to hear about your Minecraft issues. Mojang and Microsoft are aware of this issue and the confusion it is causing. We have posted it within our Known Issues page with solutions to help you out. You can navigate to the known issues page here. I will also copy the information for the Minecraft demo mode problem below.

Minecraft (PC)

• Are you receiving a Demo Version of the game when you own the full version?
  
  • Mojang has published a help article here to help answer your questions and get you to a solution
    
  • If you require further assistance, you can open a ticket with Mojang here under "Report a Concern"
    
  
  At Minecraft | Xbox Support you’ll find troubleshooting tips and links to help pages for the game, info about playing with Xbox Game Pass, and info about playing Minecraft on different platforms.
  

So, the main culprit for this issue is just making sure the launcher or app is logged in with the right Microsoft account. There are steps on how to accomplish that in the article. If there are concerns over what account now owns the licenses, you can reach out to Mojang support to get that worked out.

Hope this helps and happy gaming.

If you bought it on a Mojang account some time ago, the Mojang system should have asked you to perform an account migration to a Microsoft account.

Only the migrated Microsoft account or the Microsoft account with which you directly purchased the game can access it, if it is locked, unfortunately you will not be able to use the game.

Originally I bought the game with a mojang account (This was back in 2016 I think)

I then changed the email for the mojang account.

then with the migration, I migrated it to my current microsoft account that is not related to any of the previous emails.

The migration was successful and I was able to play game.

I stopped playing for a while, but after trying to log in with the same microsoft account that worked previously, minecraft was not there anymore.

Since I bought it with a mojang account, there is no record of a purchase/transaction.

I bought a copy of Minecraft from Mojang on December 18th, 2010. I have the transaction ID/Term Of Sale email for it still, if need be. It was originally a 'Minecraft.net Account' in their terminology, until a later date when it was changed into a 'Mojang Account'. Eventually it was to be migrated to a 'Microsoft account', which I do remember upon reveal less than 2 years ago nearly all Legacy/Alpha owners were unable to migrate/transfer to a Microsoft account (Especially if they already owned a copy of 'Bedrock Edition' which I believe I received from Mojang or Microsoft at the time of the Mojang account migration?) which I thought for sure I had done but I cannot seem to find any info on. I also did not receive many warning emails about the migration nor deadline until this past warning that I had 'missed the deadline'.

I have reached out to Mojang, and so far you are the first ones to respond!

Looking forward to hopefully being able to resolve this in a fashion that I would greatly appreciate

Yeah I still have all the emails that show ownership and how long ago I migrated the account, it's just so far all mojangs support hell is 'faq'
