Maverick717,
I also have the Grabowski panel with the Project ERJ planes installed in FS2002, but everything's fine with mine. Make sure that you have the ERJ.gau gauge file in the FS2002 'gauges' folder, as all of the panel gauges come out of this single file.
Also, make sure that you have the update to the panel - there are three zip files you need from the Project ERJ site; the base panel, the update, and the virtual cockpit files. Unzip and install them in sequence, and you should have no problem. The virtual cockpit zip installs a seond gauge ERJ2.gau, which makes the gauges appear in the VC view.
Good luck! Come back if you're still having problems. It's worth persevering, as the panel/plane combination is one of the best packages I've come across recently.
