Error: Name not available.

[-NME-M0710NM4N]

Can't get into the game. Always tells me "Name not available". Only world it gives me is "World 8 USA East Coast". Name in game is M0710NM4N

[-NME-M0710NM4N]

Weird... I changed my name on Origin but see that this site still shows my old name. How do I change it on here and is this maybe whats causing the issue of Name not available? <shrug>
