Is Miktex setup correct with Windet?
It starts by saying that a file is missing and needs to be downloadable from "http://mirror.math.ku.edu/tex-archive/systems/win32/miktex/tm/packages/" (happened a few times before, and worked with other packages).
But now, it confirms it has downloaded the file, namely ly1.tar.lzma and that zipped files are being extracted.
But then it halts and errs: ! Font \csname\endcsname=psyr at 10.0pt not loadable : Metric (TFM) file not found.
What seems to be the problem here?
