Login into your Enjin account and enter your profile's page.
Once on your profile's page, scroll down until you see 'Characters' on the left side of the page. Click it and then move your cursor over to the top left corner of your character's profile. Click 'Edit' and then click 'Delete Character'. Then click 'Add Character' to make a new profile for your character.
Once you click 'Add Character', you will be given a prompt to go to mclogin.enjin.com. You will copy this IP address and login to your Minecraft account. From there you will go to 'Direct Connect', paste the IP address, and login to that server.
When you join mclogin.enjin.com, you will be given a personalized code. If you miss this code in the chat, you will still see it again when the server kicks you. Take this code and type it into the pop-up prompt you received when you clicked 'Add Character' on your profile's page. Now you have officially made a new profile for your Minecraft character.
