I've created my account back in 2012 and used a facebook to enter it to this day, but right now when i press Login with facebook site just shows me a popup with a rotating wheel and refreshes the page. I already forgotten what name of my previous email was so i was wondering how could i gain access to my account again.
We'll need you to please email us via support@armorgames.com with the account name so that we can work with you to look into this and work with you. For the subject go ahead and mention Facebook please.
As a temporary option, sometimes clicking on the Facebook connect button 2-3 times will get you logged in if you are connecting from a WI-Fi or mobile device. There may be a connection slowing during the what I think of as a handshake between Facebook and our site to authenticate the account based on what you are describing.
