Thanks for the reference - the manual doesn't match the screen I see

According to their website I have the latest firmware however the configuration screen is not consistent with the manual ...
Firmware Version: KCORP_2.0.0.0 Web Version: 1.0.0.0

Also since they no longer have email or phone support things aren't looking good . .
