My subscription works, but cannot access account or code. Automatic Re-new?

I've set up a F-secure Freedome account with a full 5 device subscription when downloading the software onto my mac. Only now when I am trying to get another device onto my subscription I can't access my account. I have no idea of the email used for the subscription or the code given to me to access it. I have no access to the any previous email or messages regarding my subscription only that i have it downloaded onto my device. 

The only other query I have is that if I cannot access my account in the future, does the F-secure subcription re-new automatically once it has finished and if so how do I stop this without accessing the account.
