I see that you purchased the X theme before and then converted to the Pro theme.
Now I wonder if you have any problems using the Pro or X? If the problem is with Pro we can contact our leadership team to help you refund your license for the Pro. But for the X you will need to contact the Envato.
But before anything, I wonder if there is a problem you are experiencing that we can be of a help in any way? Have you checked our knowledge base?
We do not have X Pro, we have X theme and the Pro theme.
