All authors who had an existing HubPages account and had content transferred from Squidoo will have two (or more) accounts.
You have different login information for each of these accounts (email, password, etc.).
The account from which you posted this will not contain any content from Squidoo.
Do you have the Squidoo URL for your content that forwards to HubPages?
I might be able to locate the account, if it was imported, using that information.
You may also be able to find the account via the associated email address, and if you can login using it as the username, you can change the email.
If you can track down the email for any potential transferred account, you can login here.
If you need to reset your password you can do so using the email address associated with the account.
You may be able to find your content using the Internet Archive's Wayback Machine.
Please email us at email@example.com with any further information or questions.
You can find more about the Squidoo transfer process here.
