# Problem generating pdf when at adding usepackage [closed]

I've been trying to build a presentation with LaTeX but I realize that once I introduce the use of any package it can no longer generate the pdf; I mean no .aux or .bbl files are generated. So, if I write:

\documentclass{article}
\begin{document}
Hello world!
DIANA
\end{document}


It generates the pdf with no problem but when I write:

\documentclass{article}
\usepackage{float}
\usepackage{color}
\begin{document}
Hello world!
DIANA
\end{document}


Then the pdf is no longer generated... Any suggestions? I have already reinstalled MiKTeX 2.9 and it is still not working.

What are the errors you are receiving in your .log file? – Werner Sep 29 '12 at 20:35
Which editor you are using? – Herbert Sep 29 '12 at 20:36
I tried your MWE on MiKTeX 2.9 without any problems ... – Kurt Sep 29 '12 at 20:36
My suspect is that you didn't install the full version of MiKTeX and did not enable downloading missing packages on the fly. – egreg Sep 29 '12 at 21:28
Have a look at MiKTeX: no output and truncated log file. – Stefan Kottwitz Sep 29 '12 at 21:39
