Thanks to swacker and user for helping me out, some of you others will have steam and FB requests from me desperate to try to get access toy acct, feel free to ignore these
For those who asked why, I was interstate and on my phone, my phone doesn't hold a login particularly well and I got frustrated and tried to fix it by screwing with settings here and at facebook and managed to delink my account. Because it was Facebook integrated there was no password attached and my Facebook email was from ages ago and didn't exist. Hence effectively locked out of account.
I'll post more game stuff soon
