opening Ly-files

[Hombergh Henri van den GTZ VN]

Dear Colleagues,

I have started to download Ly-files from the Mutopia website only
recently. I have obviously installed Lilypond. Most of the time if I try
to open a Ly-file, only a small txt-fiel is made with the text: #
-*-compilation-*-Changing working directory to `D:/music pdf files/L v
Beethoven Quartet Opus18 No4' Processing `D:/music pdf files/L v
Beethoven Quartet Opus18 No4/violinoone.ly' Parsing...

But a PS or Pdf file is not created in the same directory or anywhere
else on the hard disk????

I have attached these 4 files, because it does not work with any of
them. 

Can anybody help??

Thanks

 Henri
