You can check the expiration date of the license you are using at any time in the Studio, and replace it with a new one, if needed. Proceed as follows:
From the Studio menu bar, select Help > About License.
The [About License] dialog box appears, showing the license expiration data and license text content.
To change the license, click Update the license and browse to your new license file, then click OK.
In the [Confirm] dialog box that appears, click OK to restart the Studio so that your new license takes effect.
The license file is automatically updated in the root directory of the Studio.
