As the error log says, the account no longer exists and has been deleted. If you had a free membership, 3 months without activity will result in the account being deleted. You can find this in the Terms of Service (linked at the bottom of every page) you agreed to when you joined the website under section 10-I, which I've pasted below for you. Since the account is deleted, it can't be recovered.

10-I. TERMINATION FOR ACCOUNT INACTIVITY
Members without a currently paid membership that are inactive for three (3) months or more may have their account terminated without prior notice or warning.

Hope that helps!
