This is my first attempt at installing the premium themes that I found here on this discussion board. Each one is a ZIP file that contains installation instructions, but I can’t extract any of them due to an unknown error. Is there a guide somewhere on how to install these?
I asked about the same issue recently. Looks like the premium themes have not yet been made public. If you pay for the themes, you would get a password key that will reveal all the files for you to extract. However, since the themes are not public yet, even though you can download them for free, you cannot get them to work.
