Missing Textures AFTER Downloading CSS

[Jbane56]

Hey y'all, apparently I used to play this server back in 2018 and I'm just now coming back to it. I installed the CSS textures which fixed most of my purple and black boxes and big ERROR signs, however upon restarting and loading into the server there were still a few things missing, like the government raid sign in the spawn building, almost all of the "C" menu was purple and black boxes, and on my stat box in the botom left, im assuming the GamingLight emblem is supposed to be there however its just a purple and black box. What should I do to fix this?. Hope anyone who's reading has a good day!
