I was playing minecraft Java edition, after I closed my world I got logged out(logged out itself). Because I forgot my microsoft password, I changed it. But now I cannot log back in and when I try to it just says that I need to create a new account. When I played with my new account it told me I had to buy one. But I thought already paid money to get one. I could play minecraft really normally but yesterday it just suddenly logged out automatically.
I could only play minecraft demo version. I'm not sure why it did this but it never happened to me.
 
can you help me? will I ever get to play minecraft with my old account again?
