That's the version that I have that I bought so I could cross-platform play with friends. But FTB doesn't seem to work with it and prompts me to buy the Java edition. Do I have to buy Minecraft again or is there a way to get it to work with Windows 10 edition? Since on the Minecraft site, I sign in with the same Microsoft account that I used to buy the game but it says I don't own it at all, when the Microsoft store says I do.
