ITRF97 reference frame trouble

I am trying to transform a shapefile in central Panama from WGS84 to ITRF1997 for a LiDAR analysis. I can't seem to load a .prj file for ITRF1997 into GMv.10.02.

Does anyone know what the practical difference between the two might be in Central America or the reason GM wouldn't read this file?

    The various ITRF models and WGS84 are basically coincident to well under the 1 meter level, so no transformations are included. If you can provide me with your PRJ file I can at least treat the datum name in the PRJ file as equivalent to WGS84 s othat you can load the PRJ file.

    Thanks,
