What is the ArcGIS error?  I tried these files on ArcMap 9.3 and 10.0
and had no issues that I realized.  (to display in a meaningful
manner, I had to change the symbology which required the calculation
of statistics in ArcGIS.  I also changed the cellsize to .1 so I could
more easily examine the pixels and values.)

Below looks like a 3x4 grid that is labeled as 5x5 but even that
worked for me in ArcGIS (didn't throw error but values were not where
'expected').

All 4 of of Even's files worked for me too.
