Hi Roman! We can help with this process. We will remove the theme from the current site it is on and provide you with credits so you can purchase the theme on your site Spirit Picture House at no cost.
When we remove the theme from your current site, it will remove any theme specific settings you have added. You may want to make a note of that before we proceed. Once you do, let us know you are ready and we can make the changes I mentioned above. :)
