Can't even get to Buy Server page
When you click on Configure Server after putting in your MC Name, you get put back to the Plans screen.
I found a pretty easy fix.
Go to the “Client Login” page, and press on "Add a service"
After filling everything out, click on the area to input your IGN, and press “ENTER” on your keyboard. (After typing in your IGN of course)
Please note that purchasing via this method only allows for purchasing in Montreal. If you need an EU Server please open a ticket with the Sales Department.
