1. You can install the script with Basic license for free. The difference is only 1% skimming.
2. When you decide to buy Professional license you just check your Basic license (in your account at our site) and upgrade it to Professional.
3. Then you go to 'System - Update' in the admin area and click 'Update current version files'.
That's all, you'll get Professional version of the Crystal Trader from that moment.
All you need to change Basic to Professional: some money and couple minutes to make 2-3 clicks It's easy.
