Darwine/WineHelper issues

Having some issues with Darwine, etc.

Darwine = "The Darwine project intends to port and develop WINE as well as other supporting tools that will allow Darwin and Mac OS X/ppc users to run Windows"

I downloaded and installed it, but when I go to click WineHelper is has a block sign on. As you can see in the screenshot.

Maybe I'm being silly, but I don't see why it's not supported on my mac. I have a MBP early 2011.

Could it be the latest update for mac? that they haven't updated. I'm reading around and many other people have the same issue from months ago.

Any guidance is appreciated, thanks.
