Error message – License Status: Your license key has reached its activation limit.
You can go to https://nextgenthemes.com/my-account/ and deactivate your sites you no longer want to use to be able to activate new ones. If you want more sites then one activated you need a license that allows more then one site.
The site you had activated was brahmitype3.mydev.ca/ . Dev site I guess. I deactivated it for you now so you should be able to activate any site you want now.
