Some EP2 textures broken

I have no idea what textures they are. They’re also broken in EP2 maps as well.
I have started up EP2 a few times to try to get them to… Initialize, I guess I could say but nothing different happened.
I verified EP2 and Gmod and they both were fine.

Is there a way I can fix this?

Map is Zwonder_3_BETA from Toybox.

Edit: Oh wow, I only just noticed the errors in the screenshot…

Afaik ep2 requires episode 1 shared.gcf, and gmod doesnt seem to be mounting it.

Well that’s annoying… So there’s no way I can fix it?
