Download Windows Media Player 2

Right click here and choose "Save Target as..." or "Save Link as..." and save it somwhere in the computer where you have access to, the "Temp" directory in "C:" drive is always a good choice (C:\Temp\mplayer2.exe). Then run the program from that directory, and play (or drag and drop) the ".dat" music files that you got from The JukeBox.
If your computer already has the program in it, it should be in C:\Program Files\Windows Media Player\

Also links to Windows Media Technologies, a few codecs (Version 8 and Version 9) that might help, and a short javascript code that might be the last chance, when things get rough (you need to download it and run it from your computer, it won't run from the net, or at least that's what I think).

The Javascript is running late, so here's the encoder that I used. Download it and install it, even if you don't use it, it takes very small space and it will probably install all the necessary codecs needed for the jod. Later on you might find it usefull for other staff as well!

Good luck!
