I want to change the default Matrix theme with PGlightbox theme. I have copied all the files to the theme folder. I have also changed the theme id in theme.inc file. When I click the gallery, it says

Configuration Error: Missing Theme
Missing Theme

This album is configured to use the matrix theme, but it is either inactive, not installed, or incompatible. To fix this problem you can either choose a new theme for this album or install or activate this theme.

I chose to install/activate this theme but I got this following error:

What do I need to do to fix it?

I wonder if I need to perform upgrade installation? The Gallery 2 i am using is the 2.2.2 version
