Contouring Question NEW

I am recieiving this error message when I click on "triangulate and contour"
"Command: tri
C:\PROGRAM FILES\CARLSON SOFTWARE 2006\LSP\CONTOUR4.ARX cannot find a dll or
other file that it needs.
Unable to load C:\PROGRAM FILES\CARLSON SOFTWARE 2006\LSP\CONTOUR4.ARX"
I am working on a 11 acre topo and the computer locks up when I try to contour the whole site. I can contour it in pieces but that is a long way around the problem.
I have removed and re-installed Carlson without any visible effect....
Any clues??
