Problem for updating from Catch Evolution Free version to Pro version

I purchased today the Pro version of Catch Theme Evolution. I am actually on the Free version. First of all, I don't find the Catch Evolution zip File in the download. Secondly, when I try to download the Pro version of the Theme on Wordpress, I only find a file called really-simple.ssl. When I download it, I have an error message from Wordpress that says that there is no style.css fils and the the installation didn't work properly. I also don't have any field to add the Pro Licence Key in the Free version. How can I update to the Pro version ?
