Hi Suhas,

That message is indicating an error during the LaTeX -> PDF step.

Why don't you take a look at the presentation-1.tex file and see where
things are going wrong.

You can probably reproduce this typeset the file (outside of emacs)
  pdflatex presentation-1.tex

Runway LaTeX arguments usually signify something like this (closing
curly brace missing).

,----
| \documentclass{article}
|
| \begin{document}
|
| \section{Runaway
|
| \end{document}
`----

Sorry, I don't have any more time to spend on this.  Maybe someone else
will be able to help.
