miktex-mf fails to create ectt1440.

[BenReish]

I ran Miktex update yesterday and after that, miktex-mf (metafont) can not finish creating font ectt1440 at 600dpi. This breaks pdflatex and a file that was compiling just fine before the update will not compile due to a fatal error from pdflatex that stems from not finding the 600dpi ectt1440 font. Looking at the metafont log, it ends halfway through a macro definition where it says it can not happen (copy) and the the log file says to "show this to someone who can fix can fix."

I've tried reinstalling miktex to no avail. I've updated the new installation with no joy.

Here's the log file from metafont.

Here is how much of METAFONT's memory you used:

So, it's a permissions issue. I reinstalled Miktex again and used the user level setting for just me instead of the admin mode for all users. Now, after updates, the file compiles and there is no error about metafont not being able to finish.
