I have a single website (Website.Org), the website contains a LOT of information so I broke it up into Subdomain.Website.Org, and simply use "The Gem" for all of them instead of just one.

Am I allowed to use "The Gem" across my different subdomains since they are all part of the same site? I did research and Envato seems to have confirmed this is ok since I am not selling/reselling it, and just using it for my site, but the Gem requires us to verify purchase each time; and so that leads me to assume that there's a possibility that this may or may not be the case if access to one of my subdomains ends up being revoked for any reason, or if there is a limit to how many subdomains (at one point my site had issues and I had to reinstall and verify twice and so if there is a counter I'm worried that may affect future installs on my subdomains).
