TopTools Remote Mgt card v2 Interface issues

[Keith Savoie]

I just purchased 3 new (old) P1218A HP TopTools Remote management cards to install in 3 NetServer LC2000Rs. When I login via their Ethernet port all looks good except when I go to the 'configuration' tab. All buttons work except 'users', 'server info' and 'networking'. When I click on any of these the applet fails and I get the following error in the java console.

java.lang.IllegalArgumentException: illegal Choice item position: -1
at java.awt.Choice.select(Unknown Source)
at cservinfo.showValues(cservinfo.java:330)
at cservinfo.init(cservinfo.java:256)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

The cards are all updated to the latest firmware that was available for them.
Can anyone help me? Thanks!
