If a complete reinstall of all packages didn't resolve the problem, I'd
suspect one of the following FAQs are coming into play:


It's also possible that you just installed with some Cygwin process
(perhaps a service) still running.  Try a reboot.

If none of the above helps, please see the problem reporting guidelines
found at the link below.
