Home page for Connect ME

I have a unit with a Digi Connect ME. When I browse to the unit using internet explorer I get the login page as requested.

However, once I log in the page turns blank and only desplays V2.0.4.0 in teh top left hand corner.

The username and password are correct and I have tried a boot action=factory command in telnet but it is still the same.

Does anyone have any ideas how I can correct this?
