# Activation FAQ

## This purchase code has already been used

In most cases, such an error appears if the Purchase Code was registered through another support account. If you do not have access to this your account follow these steps to handle the case:

* **Log out from the current account** on the support website (skip this if you is not logged)
* **Login with Envato** account 

Thus, our system verifies the owner of the license and binds the purchase code to the email that is linked to the Envato account. For previous support accounts, the purchase code will be reset.

## How to deactivate the license? 

{% hint style="warning" %}
**NOTE:**

The **license deactivation** process will automatically **remove the theme** from the website
{% endhint %}

To reset the license key from the website, go to the **MasterStudy > Product Registration** section on the WordPress dashboard. Click Deactivate button,  you will receive a notification that you agree to deactivate, press the **Ok** button and **the system reset the license key from the website and deletes the theme automatically.**

## **If I want to use** MasterStudy **on another site, do I need to buy the license again?**

Yes. According to the [ThemeForest license terms](https://themeforest.net/licenses/standard), one license key is allowed to be **used on one project**. One Project contains **one live website** and **one staging website**. If you wish to use MasterStudy on an additional project, it requires you to buy another license.

## **Can I use** MasterStudy **on a test site, then move it to a live site when finished?**

Yes**.** You can keep the theme on a staging site to build it, then move it to the live site once you have finished.
