psnGallery2 install error (WP/Coppermine Plugin)

Hi:

I have been trying to get my WP and Coppermine installs to play nice for the last week. I installed psnGallery2 according to the instructions (nice install wizard, btw). However, when I activate the plugin and click the link to configure the values (and add “wp-content” to the link on the plugin page) I get an error page that says “Fatal error: Call to undefined function: get_settings() in /home/goswans/public_html/wp-content/plugins/psnGallery2.php on line 47.”

My gallery is working fine. WP is working fine. I just can’t seem to figure out what the psnGallery2.php file needs to work right. Any suggestions?

Thanks.
