If you have the owner key and the username, you should have no problem recovering your old account. But as it is obvious that you already have it, it is possible that you are mistyping one of them.
To avoid this in the future, I recommend that you use a password manager to store all your logins, wallet address and passwords (1Password is a great option).
Hi, thanks. I have been copying and pasting. I will give the wallet a try if I get in, thanks for the advice
