Cywin problem, font not found

[Thomas Scharkowski]

After some installations to lily 2.6.0 and back to 2.4.6 I have no 
"normal" cygwin anymore. There is no home directory and I do not get 
the former <username> prompt, only "bash-3.00$".
Commands like "cd" or "ls" do not work.

Lilypond does work, but I get the following error message:

"Interpreting music... error: can't find `feta20.afm'
Music font has not been installed properly.  Aborting"

I do not know how all this is connected.

Thanks for your help,
Thomas
