At a stopping point with this theme

hey so i installed this theme and i have had some issues making it into something that i want to. first off if i delete on article the page goes white!!!! it wont allow me to make changes to the front page at all when it comes to the articles. i added an article to see if it was a feed issue. but its not at all. secondly the white screen turned into this : http://www.thegamerdaily.com/ and im not sure what to do about this error. do i have to re install joomla?. finally, how do i make this theme live posting so i dont have to change 15 diffrent modules every time i post a blog to the site. Thanks

Hi

I believe that page turned white when modules was configured to show articles from not existing categories or pointing directly to none existing articles after removing demo content. In such case I'm afraid You will have to edit each NSP module and changes it's source settings.
