I also got this same problem (token already consumed)
I know I have not merged this account yet, it was my second account with my alt and third account I tried to retrieve on Elysium account.
I know the username, email and password for the account so I hope there is another way I can retrieve it. I know you got loads of people to help at this time, so I dont expect any help now, but please PM me when you have time
thanks!
