I still think that there is a problem with the stmaryrd package and I can explain it in a reproducible way. If I compile this file:
with pdflatex, then I get this at the .log file:
<C:\\Documents and="" Settings\\JC\\Local="" Settings\\Application="" Data\\MiKTeX\\2.9\\fonts\\pk\\ljfour\\public\\="" stmaryrd\\dpi720\\stmary10.pk=""><C: Program="" Files="" MiKTeX="" 2.9="" fonts="" type1="" public="" ams="" fonts="" cm="" cmr12.pfb="">
As you can see, the document uses two fonts, stmaryrd10 and cmr12, but in the case of stmaryrd10, it uses a .pk font instead of a type 1 font. I can solve this problem and I have done so before; all I have to do is to follow these instructions:
and, when a text editor opens up, to put
there. Then, I have to move the .map files to their correct location. But the next time I upgrade MIKTeX I will have to do this all over again. It should not be necessary.
