If you receive this message, you have clicked a link from a RealAudio or RealVideo Server that cannot stream files to your version of the Player. For example, if you have the RealAudio 2.0 Player installed and click a link for clip that was encoded with a RealAudio 3.0 encoding algorithm.

If you upgrade to the latest Player, you should be able to play any content.

Note: If your system does not meet the stated minimum requirements for using the latest Player, then you are not going to be able to access content from the latest Servers. You should still be able to use the previous Players for content which is streamed from compatible Servers. For example, RealAudio Player 3.0 can be used to listen to content from 3.0, and 2.0 Servers.
