The "psfonts.map" is a necessary ingredient of any TeX distribution I
know. It contains the information how to map the "internal" TeX fonts
to the actual files on your hard disk.

To make things short, you could remove ProTeXt and install TeXLive
(inside, there should be MikTeX for Windows). This is the standard
disrtibution of TeX.
If that does not work, there are some further testing methods to
fiddle around with later (there were some nasty MacOS threads about a
similar topic recently on this list).

The empty PDF is strange and should not occur. Are you sure that you
specify the paperformat dimensions in the correct way? You can also
explicitly state the bounding box (including manually added margins)
when writing the canvas into a file. Did you try that?
