Strange DGN2200 LPC Problem

Hi,

I have a DGN2200 ADSL Modem/Router with Opendns LPC.

I have 2 win XP SP3 pc's connected wirelessly to it.

On both machines I have installed the LPC management and user utility.
-----------------
On PC #1 the utilities work fine.
------------------
On PC #2, the management utility says that I'm connecting to a router firmware that that not support lpc.

The user utility says " error could not connect to router."

The internet works fine on Pc#2 and I can login to the router's setup screen with my browser.

------------------
How do I get PC#2 to work with LPC utilities?
I am using latest firmware and utilities versions.

Thanks in advance.

Regards
