license.lic file explained
└── license.lic

Although Motorcortex components run about 30 minutes without a license (for testing purposes), to use Motorcortex components in production you require a license. After you have purchased a license for your application components you will receive a license file that needs to be installed in the configuration folder. Make sure that the license file is named correctly according to the License setting in your config.json file.
