Display of satellite data

Hi all:

I am trying to display local satellite images - a sequence of AREA files. I could load it, but nothing appears in the display. I tried running visad/examples/SatDisplay( I am using AreaAdapter to read a McIdas Area file as it is done in this example ). In the past I remember running this example with success. Now if I run without any arguments or explicitly specifying an Area file as an argument I get this exception:

[mem@xodus examples]$ java SatDisplay
visad.VisADException: Problem getting Area file directory or navigation
at visad.data.mcidas.AreaAdapter.buildFlatField(AreaAdapter.java:126)
      at visad.data.mcidas.AreaAdapter.<init>(AreaAdapter.java:100)
      at visad.data.mcidas.AreaAdapter.<init>(AreaAdapter.java:60)
      at SatDisplay.<init>(SatDisplay.java:123)
      at SatDisplay.main(SatDisplay.java:205)

[mem@xodus examples]$ java -mx64m SatDisplay AREA0007
visad.VisADException: Problem getting Area file directory or navigation
at visad.data.mcidas.AreaAdapter.buildFlatField(AreaAdapter.java:126)
      at visad.data.mcidas.AreaAdapter.<init>(AreaAdapter.java:100)

      at SatDisplay.<init>(SatDisplay.java:123)
      at SatDisplay.main(SatDisplay.java:205)

Any hints?

Thanks
