Hi Sanjeev,
   Hmm, I've just run MSMS myself on 1FPY and I get the same result, no
surface. I think this is due to the way the surface calculation algorithm
works in MSMS. I re-ran the surface calculation using the atom selection
"chain A" and I got a proper surface for chain A, so I suspect that in order
to make MSMS happy you may need to create a bunch of individual
representations for each of the chains. (i.e. "chain A", "chain B", etc..)
Try that and let me know if you still need help.

By the way the new VMD 1.8 test versions contain some improvements
to the surface display code which make MSMS an even more attractive
option. The new code can display MSMS surfaces about twice as fast
as previous versions. The new code doesn't help Surf yet, that will
require more work.
