No luck with those instructions, still no textures, not even on the main screen. Im using: 0syscall6, nonpdrm, repatch, psvshell, kubridge, and nopowerlimits.
At this stage I've got no idea if any of those plugins could be causing issues. My best suggestion would be to ask around and see if someone can give you a copy of the vpk that's already had the media.zip put into it - we've tried everything else that I can think of, and if a known good vpk doesn't work then you'd need to address the plugins by turning them off one by one, but it shouldn't be nonpdrm or kubridge at least
