Email change to a previously used email address

[davidgoodman030552 0]

I have had two Evernote accounts, one Premium and the other not. I have discontinued the non-Premium account.  The mail that I use on my Premium account is no longer going to be usable in a few months, so I need to change it soon.  The only other email I have is the one that was attached to the non-Premium account that I have discontinued, but when I try to change the email address for the Premium account to that email address, I get a prompt that tells me that that email address is already in use (presumably because it was attached to the discontinued account), and I cannot effect the change. I need to have that other email address freed up for use with my Premium account soon.  I will appreciate help in doing so.  Thanks.
