  The old VMD 1.9.1 binaries should indeed load PDB files, however
the linkage to the on-the-fly web download won't work anymore because
the PDB archive has been restructured and the old URL paths that were
compiled into the program are no longer accessible.
Try downloading your structure(s) locally and load them that way.

Can you tell us more about your 3DSystems Touch setup?
We haven't had one of these running for many years now, so it hasn't
been possible for us to test any of that functionality for a long
time, although all of the code still exists in the current versions
of VMD.
