OFFICIAL Issues with Registering your Email to your FarmTown Account

[Serenity Dilsworth]

I hope I am in the right place. My cousin hasn't played in awhile (before the slashkey site change. But she cannot access FT due to her memory loss. She is still my friend on facebook and has her farm in FT. How do I get her ID. Her email has changed and she can't recall it. When she goes to her facebook page and clicks on her browser line,, all she gets is this:
https://www.facebook.com/
no id number in the browser bar.
If I visit her farm, all I get in the browser bar is this: https://apps.slashkey.com/farmtown/play/
She is Level 973, goes by Moose by is named Pan SIms recently changed back to her real name, Serenity Feathers.
She simply cannot recall her old email. She can get into her face book.
I hope I posted in the right place. You know me, always in the wrong place. LOL
She is set public on Facebook.
Any help you can give to recover her old farms would be appreciated.
Thanks,
