1) if this error repeats, contact your host's administrator, something is wrong with the server.
2) try add in templates/<your template>/media/rm.html this:<embed src="{media_src}"
type="application/x-pn-realaudio"
hidden="0"
autostart="1"
loop="0"
height="60"
width="275"
controls="ControlPanel,StatusBar,info">
</embed>
This is just an example, so I'd suggest you do a little research on the internet on how to play RealPlayer media on a webpage.
