Hi gerryv101,
Thanks for posting and welcome to our community 🙂
Sorry to hear you've not been able to access your emails. As Graham_A has advised, if you no longer have a VM broadband account, sadly you won't be able to use the email address. These are usually removed 90 days after closing your Virgin account.
I've popped you over a private message (purple envelope, top right hand corner) to get a few more details from you, I can attempt to reset the account in order for you to gain access, but would advise you to move any important emails over to another account.
I do also need to set the expectation that this may not work.
