Having no end of trouble including a large landscape pdf in a portrait .tex document (using pdflatex).

When it does show up, only the leftmost end of the pdf shows up, now matter how small i make the scale. And i cant seem to get it to show in landscape mode at all...

Is anything wrong with the code i am using?

\begin{landscape}
\includegraphics[scale=0.1]{Appendix2.pdf}
\end{landscape}
