So I wasn't playing mc for like a month and my friends started to make a server so I wanted to play, but when I opened the launcher it said I am in demo, I logged to my other account that had same thing like a year ago and there it said it was in demo too. On the other account I bought mc and after like 4-5 months when mc was updated it said demo, so I bought mc again and it looked good for a year and now after the update the same issue is here.
