Guys I have a question. How is it possible that all the procedures (split with Gmaptool, run install.bt, open in Mapsource) are exaclty the same in two different pcs (xp sp2 and xp sp3) but the xp sp2 is working and the xp sp3 is not? I followed the procedure so many times..I am getting crazy..could you please suggest me a solution? thanks
