Samsung GT5830i?

Hi, I have completely lost the News & Weather on my Samsung,when I click on the icon I get a message at bottom of screen saying Sorry,network error.Please try later. I have been trying for weeks now at all times and in different parts of the country.I've switched it on and off a couple of times to no avail.And advice welcome,cheers.
