[Plugin: Page Flip Image Gallery] V 0.5.9.6 not working anymore

This was working beautifully; but I recently updated WP to latest version; now I notice the Page flip plugin is no longer working. Each page where I have a page flip gallery says: “Flash player not installed.” I downloaded and re-installed it three times, and Flash seems to be working everywhere else. I’d sure love to get this working again; it’s wonderful when it works.
