What information's did you provide while trying to login? It's possible that the second password they are referring to is taken from the passphrase,
nope - the second password was never set because back then it didn't exist.
1. its not the main password - which I have and which is what ^ this method recovers.. its the 2nd password that was put in place when they upgraded to v3 wallets from v2.
2. I do not have the backup file
3. Not sure importing applies to my case.
The thing with that mnemonic phrase is that It cannot be used anywhere else unlike the new HD wallets where BIP39 is used. If that solution doesn't work, you will having nothing but to wait for support answer.
That's exactly what I am doing for the last few month - almost a year .. they can't be bothered it seems... responses come once every couple month that too something that does not help..
