The registered version requires a monthly subscription license. The cost of the license is $24.95 per month.
The unregistered version does not require a license. It has all the features as the registered version but only saves, uploads or exports up to 10 items.
After the program starts, the license dialog will be displayed:

This dialog can be brought up from menu Help / License.
If you would like to purchase the monthly subscription license, click the purchase license button and you will be directed to the SellerMagic purchase web page. The web page will step you through the purchase process and after it is completed, a license key will be emailed to you.
After you get the license key through email, in the same dialog, click the “enter license key” button. In the pop up window, enter the license key and click register. The SellerMagic ALT program will contact the license server and does the registration.

If the registration is successful, the program will run in a full licensed mode.
