@MojangSupport Hi, I bought Minecraft at the beginning of July this year. First I played normally and everything worked perfect. But then I tried to change my E-Mail, becaused my account was logged in with my fathers E-Mail. Then I couldn't log in for a few weeks.

@MojangSupport Now I can log in, but can only play Minecraft-Demo and don't install the full version. What can I do I allready bought Minecraft...?
