METAFONT failed for some reason
Sorry, but miktex-makepk did not succeed.
The log file hopefully contains the information to get MiKTeX going again:
C:\Users\Esteban\AppData\Local\MiKTeX\miktex\log\miktex-makepk.log
!pdfTeX error: pdflatex (file ecsx0800): Font ecsx0800 at 525 not found
==> Fatal error occurred, no output PDF file produced!
I could not reproduce this with the provided test case and thus cannot work on this effectively. You want to inspect the METAFONT log file to see why the font could not be created.
