Please post the complete preamble of your document that produces this error.

Hi thanks for your reply

I am trying write over one of the examples in the package.
But it does not work.

I guess is an installation problem. I installed beamer again but it did not help i have the same error

Raul

here is the preamble

Code: Select all

\documentclass{beamer}

\mode<presentation> {
  \usetheme{Warsaw}
  % or ...

  %\setbeamercovered{transparent}
  % or whatever (possibly just delete it)
}


\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\usepackage{times}
\usepackage[T1]{fontenc}

\title[Short Paper Title] {Presentation Title}
\author{Raul Leal}
\institute[Universiteti van Amsterdam] 
\date[Short Occasion] 

\begin{document}

I assume that you are using an old version of the beamer package. Which LaTeX system do you use?

Code: Select all

\listfiles
\documentclass[smaller]{beamer}
\mode<presentation> {
\usetheme{Warsaw}
% or ...
%\setbeamercovered{transparent}
% or whatever (possibly just delete it)
}
\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{cmbright}

\title[Short Paper Title] {Presentation Title}
\author{Raul Leal}
\institute[Universiteti van Amsterdam]
\date[Short Occasion]

\begin{document}
  …
\end{document}

At first, add the \listfiles command to your preamble like shown above. Then search the list of used packages in the log file and post it here.

Using a typeface like Times is not recommended in a presentation. Use a sans-serif font like cmbright instead for better reading.

I use Miktek 2.4
I am using the beamer distribution that comes with the package.
I will download a newer version of beamer to see if it improves.

I use Miktek 2.4
I am using the beamer distribution that comes with the package.
I will download a newer version of beamer to see if it improves.

So we have the solution. This old version of beamer doesn't know the \usetheme command. You can check that in its documentation by getting it with a shell command.

Code: Select all

texdoc beamer

But installing a new version of beamer won't help. There could be dependencies with other packages (especially pgf, xcolor, xkeyval, …), which have to be solved. MiKTeX 2.4 is obsolete and all repositories are closed. But you could install packages manually. I recommend to update to version 2.6 of the MiKTeX system.

[RaulLeal]

Thanks!!!

I installed Miktex 2.6 and now every thing is working fine.
