I've got back in, but in a strange way.
I took your advice and looked in the junk folder (which I didn't do before) and found the email for Unity.
So I pressed the link and copied the password. However...............I found myself back in the Unity1 account.
Then I logged out as Unity1 and went back to the email, double checked it was addessed to Unity, then went to my bookmark link to the site and used the pswd.
I'm back
Thanks for mentioned the junk folder. Because all my emails from the site always went into the normal inbox I never thought to look there.
