Two things:
 
1. You really should be using sander.MPI for parallel calculations.
2. Do you think you could post your inpcrd and prmtop files for us to test?

Although I have yet to determine why, I re-made the .inpcrd and .prmtop
files in xLeap, and attempted to run the job again. This was my error
message this time.... any thoughts?

Regarding using Sander on Amber9 to run an MD simulation, my pbs script
included AMBERHOME/exe/sander and was receiving this error message:

It was suggested to me to add .MPI after sander (AMBERHOME/exe/sander.MPI),
which I did, and now my error message reads as follows:
set_SCR: using existing PBS job directory /scratch/batch/204612
forrtl: severe (64): input conversion error, unit 8, file

Is it my .prmtop file as the 2nd line indicates? .MPI was not used in the
PBS script in the tutorials (which I executed successfully before attempting
my own project) and that is what I am using as my guide. Help?
