Accounts mess up

I have a problem. My computer died on me so I had to get a new computer. I have AVG Driver Updater (701 purchased 03/06/2016-33*****)
AVG PC Tune up (703-082****) purchased 01/09/2016  
AVG VPN (1088-300**** DR purchased 19/10/2017
I want to have these on my present computer but don,t know what to do as I mcan't get into my old account. The VPN is in my account but that is all I can find. My e mail addresses are as follows. 
shirley.d*****@o2.co.uk  No longer in use as o2  just closed it.
shi*****@gmail.com  this address is the one that I am using. 
At the moment I am using a trial version of Tune Up and VPN and I will be billed for these when the trial is up and I already have paid for both.
Please can you help me Many thanks…Shirley
