Purchased Minecraft in Beta, apparently called "Java Edition"

"Java Edition" now includes a free version of Minecraft "Windows 10 Edition"

Mojang account website page is giving errors when requesting the code to unlock "Windows 10 Edition" from "Java Edition" 

Please fix website or email/DM me so I can get code for "Windows 10 Edition"

Attached screen shot is showing part of the page and the link I am attempting to use, but not working properly.
