We ran into the same problem after applying SP1 and it still seems to be broken after the latest Component Patch was installed. I opened a support request regarding this and they are working on resolving it but didn't have a time frame for me. To work around the issue we just manually modify the registry on our Remote Console (we use a terminal server). Since this isn't something we are changing on a regular basis it hasn't been an issue for us.
HKEY_LOCAL_MACHINE\SOFTWARE\Managed Planet\Console Extender\Plugins\
