I've been trying to log into the game with my older account (which I created during MoP) and now that I'm trying to play on Legion, it just won't let me log in. It says "We couldn't Log you in with what you just entered. Please try again (BLZ51900003)"

I've researched this particular error code and found it might be because I need to activate Legion login, yet there is no option to do so in my account. How do I fix this?

This error is most commonly caused when you try to login with your username. Due to Blizzard adding additional protections against private servers you need an E-Mail address to log onto our Legion realm. To create one, please log  into your account on https://monster-wow.com/and have a look at your Membership info on the right, it looks like THIS
The highlighted "Legion Login: GENERATE IT NOW!" text can be clicked on to link an E-Mail address to your account. You need to use that E-Mail address to log onto our Legion realm. Note that if you also play on our Cataclysm realms, you will continue to use your regular account name to log onto those.
