Thank you for using our theme.
We checked your code and see that you tried to activate it on multiple domains (screenshot in private content).
We have reset the purchase code limit and you can still use it. But keep in mind for future references:
You can use 1 license for 1 project (dev and production sites) according to ThemeForest license policy https://themeforest.net/licenses/standard
One standard license is valid only for 1 project. Running multiple projects on a single license is a copyright violation.
