Can I upgrade my extension license?
Yes you can upgrade your purchased extensions to more licenses or into a bundle. Once you login to your account select License Keys tab.
Next press the View Upgrades option on the item you want to upgrade.
The next screen will display the available upgrade options for the selected item, in this case upgrading from a single Sliders purchase.
From there you can select the Upgrade License option and complete the purchase.
This will allow you to install the extensions on additional websites and be able to get support and download updates for your new websites.
