Uh, anyone bought a name change recently and have this problem?

I bought a name change for my main- but on the character select screen, when I try to right-click > change name, I get the message 'A name change is required to log in with this character'- yes, alright, but there is no prompt whatsoever to change my name. Nothing popping up except for that message. I had tried restarting the game over and over again and right-click > change name, still no go.

And now I can't login into my main to enjoy sb... >:
