Login Failure on new computer only

I recently bought a new computer and trying to use Thunderbird for my ATT/Yahoo mail like I did on my old computer. I keep getting a login failed message on my new computer. I moved my profile over from my old computer, all passwords and settings exactly the same. I can still use Thunderbird on my old computer, but it won't work on the new one. What am I doing wrong?

The secure mail key that replaces the account password in TB has to be different for each computer, even with the same account.

Thanks for your reply. Okay, so how do I create a new "secure mail key"?

Remove the entries from Saved Passwords in Settings, restart TB, enter the key when prompted for a password. To create the key, see:
