As usual the logs only show what happens, but they don't show why.

I installed OpenSSH-5.8p1 on Windows 7 64 bit.  I tried to connect from
32 and 64 bit Cygwin machines using ssh 5.8p1 and I tried it from a
Linux machine with ssh 5.5p1.  No problems at all.  I removed the ECDSA
host key to get the same "Can't load host key" message... still no
problems at all.

What about deleting and reinstalling sshd as a service?  Maybe that
helps.  

  $ cygrunsrv -E sshd
  $ cygrunsrv -R sshd
  $ cd /etc
  $ mkdir OLD-KEYS
  $ mv ssh_host* OLD-KEYS
  $ rmdir /var/empty
  $ rm -f /var/log/sshd.log
  $ ssh-host-config
  $ mv OLD-KEYS/* .
  $ chown cyg_server ssh_host*
  $ cygrunsrv -S sshd
