In pcb view drag the silkscreen image in core parts/pcb (circled in red here) in to the sketch, then in Inspector (in the lower right window) click on the load image file section, select the svg you posted and hit load. That will load the image as you see here. Drag it to where you want it.
Apparently yes (I hadn’t noticed that!) Fritzing isn’t liking something about the format of your svg, but I’m not sure exactly what. I tried ungrouping it,but that doesn’t help. The image displays correctly in Inkscape, but not in Fritzing. I’ll poke further and see if I can figure out why. My guess is the order of the paths somehow.
OK, I had to simplify your svg (removed a bunch of redundant paths and remove stroke widths leaving only fill on the character paths). With this svg (which the forum won’t upload so down load this file and unzip it to get the svg!):
This is not really a .fzpz file (which is why it won’t load in Fritzing) but rather the logo.svg file zipped and set as a .fzpz file because the forum will recognize a svg file even if renamed (we used to be able to use logo.fzp, but no longer can as the forum recognizes it is an svg and tries to render it.) and won’t upload .zip files. To get the logo.svg file just unzip the logo.fzpz file and it should appear (I use 7zip to do this, but any unzip should work.)
