Can someone please check for me if this texture works on your PC?

textures/impdetention/512_512lights

When I try and use it I get the message:
Warning: Activate shader failed for textures/impdetention/512_512lights

In-game SS of console

Is this just GTK Radiant acting up or does this brush not work on other PC's? My clanmate says that texture is working for him. Is it possible my base is corrupted?

You've got a screwy custom shader in your base, most likely from the matrix map, or the JK2 FFA pack.

mmm thanks I didnt think about that.
