Can't install downloaded skins from this site.

Hi, new guy here. I came across Xion on the WinCustomize site and decided to give it a run. I am using the most recent version on WindowsXP Pro. I have no trouble with the Xion skins that I download from WinCustomize as they are automatically installed. However, the skins from this site are not working.
What I am getting here are Zip/WinRAR folders containing PSD files. I can open the PSD files using notepad but all I see are lines of code. If I drag the PSD file into the Xion player it will install the new skin but that skin only lasts as long as the program is open. How do I convert these PSD files into the XSF ones so they will permanently remain in the skin collection? Do I just reame the files changing the ending or is it something different?
Right now they are all in the Skin Folder within the Xion Folder. I notice another folder called Interfaces that also has working skins. Should I be downloading/extracting the Zip/WinRAR into both folders or is the problem elsewhere? I really like this music player so I hope to get it set up correctly. Thanks.
