Unable to access my Trello account that was created using an email account that is no longer active

[Perlin_ Jeffrey _CMS_CTR_]

When I first opened my Trello account I used an email address that is now inactive (my company merged with another company and we have new email addresses now). The new company configured the system to forward any emails sent to my old email account to my new email account some time ago. Even though I had a new email account, I was still able to access Trello using my old email account for some time now (several months). 

I was able to access Trello this morning, but at some point I was automatically logged out and when I try to log in using the original email account that I opened the account with I get a message indicating that my account has been deactivated. It also said it would send an email to me with more information about who I should contact to get my account re-activated.

I have not received an email indicating who to contact. 

If I try logging in using my current email address it does not have access to the Trello boards that I was using. It's as if I am setting up a new Trello account instead of accessing my existing Trello account (which logically makes sense). 

Is there any way I can access using my old email address (the one that's associated with the Trello account I use)? If so, maybe I can export what's contained in there, open a new Trello account using my new email address and import the work there?

Thanks in advance for your assistance!

Update: I checked to see if emails being sent to my old email address are still being forwarded to my new email address and they are being forwarded. I sent a test email to my old email address and it was forwarded to my new email address and appeared in my inbox, so I don't think that is the problem. My account just seems to be deactivated for no reason - I use my Trello board all day every day so it can't be because of inactivity.
