hi, I am bhavnausing ArcMap9.3 with Windows 7 64 bit. I installed HEC-GeoHMS version 5.0, ArcHydro tool9 for watershed modelling. when i tried to generate CNGrid (input fil, Lulc_soil_union and CNLookup table) from utilities of HEC-GeoHMS, its doesnot generating CNGrid (Grid formate) and showing the massage below
