Its been a month so I decided to create this because it says to contact support I think this is that. When i first open mincraft it says error number -9 i have no clue what that means but it says theres an error with my acc and i cant use market place untill its fixed. When i join my world and try to invite my friends it says it cant connect to multiplayer even through im connected to wifi i have tryed leaving minecraft and joining back but that didnt fix it. My friends are telling me to delete minecraft and redownload it but im scared that might make me loose my worlds i dont want to loose them. Also another thing that i dont know is connected to this one time i joined back into my world and my whole inventory was empty i didnt have much but it was kinda confusing
