I've had to reinstall MikTeX after a system update, and a file which used to compile all right is now returning a strange error:
Trying to make PK font ecbx1000 at 600 DPI...
The PK font file C:\Users\lleszek\AppData\Local\MiKTeX\2.8\fonts/pk/ljfour/jknappen/ec/dpi600\ecbx1000.pk already exists.
LaTeX Warning: There were undefined references.
(see the transcript file for additional information)
!pdfTeX error: pdflatex (file ecbx1000): Font ecbx1000 at 600 not found
==> Fatal error occurred, no output PDF file produced!
texify: pdflatex failed for some reason (see log file).
I am perplexed. First, it says the font cannot be created because it's already there. Then it says the font cannot be found.
To make it even more frustrating, my source file never explicitly uses this particular font (at any scale), so it must be somewhere inside some macro in some package...
For what it's worth, I am now using pdflatex to add picture files in .eps format (it's while googling for ways to do that that I came across this forum). My old LaTeX environment accepted .eps as its native image format, so to speak.
Sorry if this has been answered somewhere already, but I drew a blank (quite a few blanks, in fact) when looking for it, perhaps because I didn't know exactly what keywords to look for.
Thank you in advance for your helpfulness,
