Not able to connect to the marketplace

For a couple days now I'm not able to look at an item in the marketplace. Every time I tap on it, it does it's little sliding motion thing then it says "were unable to connect to the marketplace maybe check your internet connection" but everytime I do this I'm on wifi and it's a lot of wifi too. And now I can just look at the titles and sometimes the pictures on the home screen of the marketplace if I'm lucky. One time I spent about 20 minutes waiting for it to load and.....nothing happened. And it keeps happening. Can you please get this resolved I really want to play the new free maps.
