yes but to complete email  change they send a code to the old one, if you cannot access old one, you cannot change it... no solution

@mariapinto If you no longer have access to your email address our Support Team can assist. 

We can only make this change over the phone. This is to protect the security of your account.We offer phone support from 6:00 AM to 6:00pm, Monday through Friday. We also offer callback option so you don't have to wait on hold if there is a queue! 

Please let me know if you have any other questions!

Can I please get the number for phone support?   I have the same issue, no access to the email tied to my account.  I keep getting the links back to the community support but can't find a phone number anywhere to call tomorrow.

Thank you for the help,

Derek
