I Drive for WordPress issues

Im hoping someone can help me with an issue I have with the IDrive for WordPress plugin. After installing and activating, the settings page shows none of the graphics that can be seen on 3 other sites on which Im running the plugins settings page, header graphic, gradient login tab and although you can input user and password the buttons to login dont appear to do anything. Ive tried a few automatic installs and a manual one but with no luck – tried deactivating other plugins but still nothing. WP version is 3.0 .Any clues would be much appreciated.
