Did you change the user account under which postmaster is running?
If so, then heed the warning in the README:

2. It is recommended to delete all cygipc temporary files
(/tmp/cygipc* and /tmp/MultiFile*) before starting postmaster under
a different user account. Otherwise, postmaster will fail to start
due to IPC errors.

If not, then sorry but I have no idea what the problem is.
