I try to put my skin but when i start the world my skin looks like steve, i tried to uninstall and install laucher but nothing worked. My minecraft was purchased on another site that gave me the code that I put on the mojang site then said it worked but I went to test the skin and it didn't work can you tell me if the problem is why I bought it on a different site?
