I ran the calculation and got the following error message written to the
screen:
Error opening unit 30: File "_MMPBSA_dummyreceptor.inpcrd.1" is missing
or unreadable
Did you see something like this, also? Something similar was also at the
end of the mdout file.
Once I fixed this bug the calculation ran just fine for me. Let me know if
this is actually your problem and I will let you know how to fix it.
