Hello,
I already had Cornerstone installed on my wordpress, it’s a very old version and i need to update it, but in order to do so i need the Purchase Code, so this morning i purchased Cornerstone once again to obtain another one because the previous one was made by someone else i no longer have communication with. I can’t seem to get it to work, I’ve tried several codes provided but none work and i need to update asap.
Please help. 
Thanks
