Helix player: The following components are missing: ...

[James Jones]

I took advantage of a web page that gave instructions on installing the 
Helix Player for FC1...and it just worked; life was good.

This morning, though, I get the following error message when I try to 
listen to streams from either of the Iowa college stations I listen to 
(URLs http://www.woi.org/stream/woi-am.ram and 
http://www.kuniradio.org/kuni.ram):

    The following components are missing: slt/Cache/<long hex number>

and it refuses to play. (I also get a popup with "No plugins available 
to playback this media (0x0040011)
file:///home/jejones/.mozilla/default/cg60erpa.slt/Cache/<same long hex 
number>". (Not sure why it thinks that, since the Helix Player window 
does in fact show up, and consulting about:plugins and /etc/mozpluggerrc 
say they'll use the Helix Player for the appropriate kinds of files.)

Any suggestions would be greatly appreciated.
