When I try to open the Market, I'm frequently met by a white screen saying "No Connection" with a retry button, which does nothing. There's noting wrong with my network connection. I'm connected to the wi-fi in my house, all other apps using the internet are working fine. I'm not sure exactly when this started, but I updated a lot of apps recently, Market may have been one of the ones that was updated

 

ok, how do I do that?
