I can't install backgrounds for GMod10

Today I downloaded this background with music, http://www.garrysmod.org/downloads/?a=view&id=74732. And I can’t seem to get the background to install, but the music works fine when I install. It told me to extract to materials > console, and I put the files there but it wont install. I’ve tried other backgrounds in the past and had the same problem. I’ve deleted the old background files that didn’t work but I still can’t get this BG to run on startup.

Any help is appreciated, thank you in advance.

did you even rename it to the original background files name? “background01” I believe it is. Not sure since I don’t install backgrounds.
