I need help with my spray.

Hi, I’m trying to get my spray: http://www.fpsbanana.com/sprays/55950

To work in GMOD. It works in TF2, but for some reason it just gives me a purple checkerboard on the little box next to Import spray when I load it. It is in .tga format. Would someone PLEASE help me?

edit: It doesnt work in TF2 either.

needs to be JPEG

You see the supported file formats in the screen where you can “upload” your spray into a game.
