I cannot change my preset username to my wishing username. They automatically gave me the name Guardian7011 and since i couldnt change my name.. It tells me that i can only change my name once and i didnt change it at all since they gave me the preset name. I dont know if this is an error or the problem is the name i want to change it to. Either way i wanna change my username and they dont let me do it. I dont wanna be called Guardian7011.. Please help me!!!
