Minecraft Account not working properly

So I have founded out that my Minecraft Account named CookieMedSprus isn't working anymore. This Account have worked out properly, and I bought it for like 2 years ago. But now when I log in, on the normal Minecraft Launcher, it says i can only play Demo version. It says I need to buy bedrock, but I have already bought that 2 years ago. 

 

So in summary, I can't log into my Accont CookieMedSprus, and play on it.
