Cost Distance Tool Failure

Question asked by rangermry on Jul 15, 2013

I have a cost distance tool setup for a batch process.  To take a bunch of inputs from a folder and then use the same cost raster and file saving conventions.  My tool will run but it never runs the process of the cost distance.  It just sits there and does not run.  I tried making it with arcpy the regular way and tried with gp arcpy.  Either way it does the same thing.  Anyone know what I can do to make this run?
