[MiKTeX] MikTeX no longer working? [Very bad]

[Mau V <mv...@ya...>]

I updated tonight (april 9) to the latest release and I get  an error. This is what I get:

This is pdfTeX, Version 3.14159265-2.6-1.40.19 (MiKTeX 2.9.6650 64-bit)

Sorry, but pdflatex.exe did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

  C:/Users/Vianello/AppData/Local/MiKTeX/2.9/miktex/log/pdflatex.log

You may want to visit the MiKTeX project page, if you need help.
