Having never used a commercial text editor, I don't know if its integrity. What happens if you use a different editor, like vi/emacs (Linux/Mac) or Notepad (Windows)? What operating system are you using?

The only times I've had pdb2gmx die when reading atom types are when the line endings are bad, so I would strongly suspect this is your issue.

    Did the program hang here? Did it crash? What modifications did you make,
    and to what files? Are you using a plain text editor that properly treats
    newlines?
