Sirs/madams

I want to run RegCM3 over a mountaneous region and for that matter I want to use USGS Landuse categories. I have downloaded GTOPO30_3MIN data  and placed it inside the DATA file, but I get the follwoing error:

 ERROR OPENING ../DATA/SURFACE/VEG-USGS.03 FILE: FILE DOES NOT EXIST
4820 IN SUBROUTINE RDLDTR

when I lists the DATA/SURFACE directory....I find the data there as under:

nmg@nmg:~/JP/RegCM/PreProc/DATA/SURFACE$ ls
*  datalinker.x  GLCC3MIN_BATS.CDF  GTOPO30_3MIN.CDF

Then I made a directory VEG-USGS.03 and put the GTOPO30_3MIN.CDF inside it....when I run after that I again get an error which says as follows:

 ERROR OPENING ../DATA/SURFACE/GTOPO30_3MIN.CDF     FILE:  FILE DOES NOT EXIST
4810 IN SUBROUTINE RDLDTR

What do I do? Where am I wrong? PLEASE HELP!
