problems accessing creativecow.net

hi- anyone have any ideas how to fix this? or any ideas?

I'm having issues accessing creativecow.net. I know their site isn't down because I can access it from my iphone. But on my home network I can't get to their site using any browser or anyone of my machines. I called my isp and they said it's not a problem on their side, and they could access it just fine. I'm using a linksys router, i've tried restarting that. But outside of that I'm not sure what else to do to troubleshoot this, it's been going on for about a week. Any advice would be great!

ps
well, I guess when all else fails, wait two weeks and have the problem just go away on its own. Weird.
I can't complain.
