Minecraft ever bought, now it is gone?

I've been playing Minecraft for a while. I have not been on for a while now and suddenly I log in and it says that I need to buy Minecraft again. How can that be?

Had that synonymous on the desktop, but from there it has also disappeared, generally as a program…

Just need proper email & password, you can always blow it down. Only with your right acc without data not.

as far as I know

I'm registered correctly and still I can only buy it. If I want to download, always go to the email address of my parents and then I should buy it

Then you are not registered properly!
