This is because you deleted the first line:

-1:7:-1:-1

in the file you downloaded as you mentioned in an earlier message.
Contrary to what I told you before, the /resources/grib/tables/ spec
does not look at the one in the JAR file (at least from my experiments).
It will still be relative to the grib1lookuptable.lst file.

The one in your DefaultIdv/resources/grib/tables/ must still have that
line in there.

You can unpack the nc2.2.jar file and look in the resources/grib/tables
directory.

It's just the first line missing.  If I delete the first line in my
file, I get the same error.
