Here is a strategy that might yield success -
1) Use ptraj to output a series of .pdbs from your .crd file. If that
does not create useful .pdbs, something is fundamentally in disagreement
between your prmtop and crd files, as Dr. Simmerling has suggested. If
you get reasonable pdb snapshots, then on to #2 ->
2) You might try using chimera or mddisplay or molview etc to visualize
your trajectory. These may not give you the movie-making power of vmd.
But, if they work, you will be well positioned for #3 ->
3) Write the authors of VMD directly with details of your success
everywhere else.
