When I clicked to redeem the Minecraft Windows 10 edition in my Mojang account I was redirected to the login page of the Microsoft account, then I accidentally close the browser. I re-opened it, and enter my Mojang account, clicked in redeem again and then i got this error:
Server Error in '/' Application.
