Cannot run kotex

I try to run:

\documentclass{beamer}

\mode<presentation>
{
\usetheme{default}
}

\usepackage[ngerman]{babel}
\usepackage[cjk]{kotex}

\title[Vortrag]{asdas}

\author{yxc}

\date{xy.\,Oktober 2018}

\begin{document}

\begin{frame}
\frametitle{(문)}

\begin{center}
Test
\end{center}

\end{frame}

\end{document}


But I get the following message:

Sorry, but miktex-makemf did not succeed. The log file hopefully contains the information to get MiKTeX going again: C:\Users\xxx\AppData\Local\MiKTeX\2.9\miktex\log\miktex-makemf.log Sorry, but miktex-makepk did not succeed.

• Cannot access my LatexDoe account, so I use a new one. All cjk-related and kotex-related packages are installed according to the MiKTeX package manager. What can I do? – latexdoe2 Sep 9 '18 at 10:27
• Welcome to TeX.SX! It works fine for me. - 1. Could you run any other small test document? 2. Have you checked all packages? – Bobyandbob Sep 9 '18 at 11:59
