X11 Help!?!?

So I download this app called Darwine WineHelper. WineHelper is basically a program that allows you to open .exe files and Windows apps on Macintosh. It's a bit like CrossOver and VirtualPC. Problem is I can't use those programs because they are "not supported on my system". So I can only use WineHelper.

If I want to use WineHelper I need X11 for Mac. So I download the X11 installer off the Apple website. When I open the installer it tells me that I have newer software on my computer. But WineHelper still won't work .

What do I do? I can't find this "newer software" so I can't unistall it. And WineHelper won't work. I've tried pretty much every other PC to Mac software. Is there anything I can do?
