Earlier this week I purchased the Pro version, as I needed multiple play list.
Yesterday I made our site live. http://aquasoundentertainment.com
WordPress is installed in a folder called wordpress
When I made the site live I changed Site URL to the root but kept WordPress in its own folder. Now it is impossible manage any of the songs, as I get a page not found error. Temporarily I reverted the Site URL to http://aquasoundentertainment.com/wordpress and was able to Manage Songs. However I don't want to keep it this way as I don't want the site showing in a "WordPress" folder.
Note: Today I updated to Ver 1.2, which makes no difference, It still shows Page not found.
The problem appears to happen when the Site URL and WordPress URL are in different folders.
