Chique Music – No license key option in existing free site after purchase

Hi, I installed the free version of Chique Music and decided to upgrade to Pro. Did that and now have a license key. Unfortunately the instructions re how to install license key, as described in this help topic - <h2 id="question-installation-how-to-activate-license-key" class="faq-question question">How to activate license key?</h2> do not correspond to what I see in the theme options. The activate license key option is not there. How can I install the license key for my purchase. Will I need to download the pro template and install it on my site, if so would this replace the work I have already done on the free version? I tried linking my url in my account page, but this didn't work. I deactivated the link but still could not see the license key tab in the theme options. Thanks Geoff
