are you sure you are using still the same email address? if you change email address, it will create a new account (if you use a third-party log in, it will check the email linked to that account)
If you are sure you are still using the same email address and you are unable to log in it may be that you have a duplicated account. To solve this issue you will need to write to email@example.com.
