Upgrade from 5.2.1 to Latest

[Tpepperl]

I am working with a site that has ver 5.2.1 EzGallery Pro and I am looking to upgrade to the latest version. 
Where do I find the files to upgrade and is there a license file?

I see the link to the license page but no link to download the software, or am I missing something??t

Is the license key in one of the configuration files somewhere? The person that set this up is no longer associated with the group and we don’t have the original email. 

Where can I find the license key?

It was in the original sales email.

It was in the original sales email.

How do we recover it if “we don’t have that email”?

I would need to know some information either the old email... old domain something to see if i can find the license.
