There are lots of reasons this can happen, the common issues:

 * The payload can't connect back to you due to local firewall rules
 * The payload stage is blocked by AV or HIPS software
 * The exploit target was manually set to the wrong one
 * The target system has some non-standard configuration

Check your local firewall, try switching to bind_tcp payloads, and try
using a different payload entirely (shell, meterpreter, etc). Keep in
mind you may need to reboot the target between attempts.

If the target does *not* crash after a few attempts (PIPE_UNAVAILABLE
errors), then the target is not actually vulnerable.
