Hi Ernest. We need to do some sleuthing here. Please try to open your data with a more current version of the IDV. Please: 1. Update to a current version of the IDV (2.9u3). 2. If 1 does not work, get the IDV from the nightly builds (http://www.unidata.ucar.edu/downloads/idv/nightly/index.jsp) and try gain. Keep us up to date on your progress.
