So I had a Premium Rank on this server when I played 4-5 months ago. I logged in the server today to start again by I don't have my rank anymore. My friends say that its because I changed my minecraft name. Can I have it back or a refund? Thanks.
Your rank is tied to your in-game-name, not your Mojang account. You will need to sign in using the in-game-name you donated under. If you want the donation moved to another name, you will need to purchase an account donation transfer: http://minebuilders.buycraft.net/category/586277
