BProjection Addon Won't Enable

I’m trying to install the BProjection addon. I’ve downloaded the .py and installed it in blender and it looks all fine, except when I click the check box to enable the addon, nothing happens… Anyone know why this is happening? I’m running the latest test build of blender 2.64 on my MacBook Pro (last years version. Not the very new one that just came out last a month or two ago) and I re-downloaded version 2.63 but it didn’t fix anything. Anyone know why this is happening?

I had the same problem. If you switch to Texture paint, it should come up on the side. Just make a UV map with an image, you can use your clone brush and start working!
