there are two likely options: your file is corrupt and ngmx can silently
fix it, why the molfile plugin cannot, or incompatible changes in
the .trr that are not (yet) supported by the vmd plugins.

can you produce a very small file that reproduces it and upload it
to the VMD public project BioFS (just create a new directory under
testfiles) so that it can be verified and (hopefully) fixed.
