I have issues connecting to the Technic Launcher. I just bought Minecraft: Java Edition and I bought it using my Microsoft account. I type in the credentials and it says that there's an error and my username or password are invalid. I used the email and password I use to connect to the Vanilla Launcher. They work, I have no issues. I think it might have to do with the fact that I bought only now the game and created the account and the account I use is a Microsoft account. How can I solve this?
