Settings->More->Apps Scroll down to system apps and locate the buzztv app. Select it, and then scroll down to Clear Data, and then back to home and relaunch buzztv app. This should ask you again for all your server info.
Sometimes it is just the cache, so before clearing DATA, you can try just Clear Cache (similar screen as clean data, just different option).
What service are you using ?
