If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

Best Answer

I get the same error with MikTeX 2.9, WinEdt 7 on Win 7. There is an undefined char (german umlaut?) in the pdfauthor property. If you remove/replace this character LaTeX runs until the \newtheorem{example}{Example} definition. Here one get the error that \example is already defined. Rename it and LaTeX compiles the whole document.
