To start, make sure you've followed the instructions at https://www.nextide.ca/dokuwiki/doku.php/nexpro_theme
before you go any further, especially under the Required Code
and Important Note
The theme worked great for me when I downloaded it and followed all the instructions, only difference for me is that I'm on an Apache server, not IIS 6.
Hope this helps!
