Thanks: please do rate Xy-pic on http://sourceforge.net/projects/xy-pic/ !

The xyluat font is provided as metafont sources at three different sizes 
(xyluat10.mf, xyluat11.mf, xyluat12.mf) and as PostScript/PDF Type 1 fonts 
(xyluat10.pfb, xyluat11.pfb, xyluat12.pfb). It looks like you installation 
cannot find these - did you install them where such files are expected by 
MikTeX? Some users report that one must use the 'updmap' utility to update 
the installation to see new fonts but I do not know if this is the case 
with MikTeX or whether MikTeX has a similar setup.

Xy-pic never contained any ".cfg" files in the standard release so those 
must be MikTeX specific.

This looks like the same problem except with the "xylubt" family of tips.

With "the whole procedure" I assume you followed the directions in the 
INSTALL file? When you did, where did you install the files in steps 4, 6, 
and 9?

The problem must be with your setup as your file does not actually use the 
Lucida arrow tips (xy-lu-at/bt) anywhere. My guess would be that you get 
the same errors with *any* Xy-pic file?

Either way: your file works fine for me with a standard TeX Live 
installation. Except for one surprise: you have

  \usepackage[All]{xy}

which does not work: it should be

  \usepackage[all]{xy}

(notice the change of case). With that change the file works just fine for 
me with 3.8.3 using pdflatex; I have attached the result (the 
StefanoPascolutti1.* files).

\xymatrix is defined to build a TeX "box" with the same reference point as 
the top left entry, which results in the spacing you get. If you wish to 
change that all you need to do is wrap it in a suitable box to recenter 
it. I have done this in the attached StefanoPascolutti2.* files, where you 
may find the spacing nicer.

> Thank you very much in advance for the time you'll spend helping me :-) 
And

You are welcome: I hope you'll find out what to do to fix the MikTeX 
setup; once you do then *please* post your findings to this list so others 
can avoid similar problems and I can include appropriate notices in the 
INSTALL file for the next version. As a first step it would be god with an 
account of how precisely you followed the INSTALL file and installed 
Xy-pic, as mentioned above.

Enjoy,
        Kris
