Beamer - undefined control sequence

You are not using the newest beamer version. The newest in miktex is beamer 2010/06/21 development version 3.10. Your version is beamer 2007/03/11 cvs version 3.07. As you have beamer in one of your user roots, you will probably have to run the update manager in user mode to get the newest version, or manually download the newest version.

The error message itself is a bug in beamer. I have seen a posting about it 2 or 3 ago. \thispdfpagelabel is defined by hyperref only if pagelabels=true, but beamer used it also in dvi-mode. The problem has been obviously corrected. I don't get an error.

If you don't want to update you can try

\providecommand\thispdfpagelabel[1]{}
