Salamander Grand Piano V3 sfz

I've recently downloaded the Salamander sfz and imported every associated file (wav included) into the Soundfont folder, however every time I attempt to play it in Zerberus, no sound comes out. The other sfz files I have also do not play in the synthesizer, and I presume it is due to the abundance of velocity layers that hinders Musescore's ability to read. The sf2 files work perfectly fine though.

I have searched previous related support questions in this forum, but do not seem to understand any deviation from the steps I took. Also tried factory resetting twice to no avail.

Help would be much appreciated. Thanks.
