I cannot get the Windows 10 version of Minecraft by logging into my Mojang account. I bought it April 9, 2011. When I click "claim your free copy," it says "Error! It looks like we've temporarily run out of gift codes for Minecraft for Windows 10. Don't worry though, more codes should be on their way. Please check back later!"

It appears this bug might have returned: https://help.minecraft.net/hc/en-us/articles/360038403371-Windows-10-Code-Error

Can someone hopefully fix it before April 20? Please and thank you!
