Why do I get "Missing Plug-in" errors with RealPlayer?
If you receive a "Missing plug-in" error message in RealPlayer when you try to play music or video on the Internet, it means the clip you are trying to play uses a format that is not automatically installed with RealPlayer. "Missing plug-in" can also mean that the clip was not created or set up correctly. Manually installing the RealPlayer plug-in software, removing and reinstalling RealPlayer or contacting the Webmaster of the site where the error occurs will usually resolve the problem.
