problems with midi2ly

[L Bowles, Engineering 02]

Hi.

I'm having problems with midi2ly.  I had it working fine until a few weeks 
ago when I updated Cygwin.  I've since uninstalled and reinstalled Cygwin 
and lilypond from scratch (including some of the earlier versions, in case 
that was the problem), but I still get this message when running midi2ly:

Traceback <most recent call last>:
 File "/usr/bin/midi2ly", line 43, in ?
   import midi
ImportError: dlopen, Win32 error 126

I also get errors when trying to run lilypond on .ly files which were 
created by midi2ly itself, when it was working on my machine.

What could be going wrong?

Thanks,

Lisa Bowles.
