Hi Matt,
    It is the problem of missing index table, the IDV may not be able to 
include all the important index tables in its release, however, the user can 
add the index table, here is the userguide:

http://www.unidata.ucar.edu/software/idv/docs/userguide/data/GribTables.html

If you know which table this grib2 requires, you can create one and add it in 
your local machine.
