Mac and Plug in

I have a mac and had to reinstall my OS and I lost my plug ins for the africam. I have reinstalled the Flip4Mac but it still says "The page “Wavelit.com | Africam” has content of MIME type “video/x-ms-asf-plugin”. Because you don’t have a plug-in installed for this MIME type, this content can’t be displayed."
Can anyone help me find this plug in?
Thank you!tara
