Struggling with this program

I have been unable to add most of the new news feeds I want and rely on. They are all working feeds in a program called Vienna. I tried to copy/paste the URL but it does not work consistently. Perhaps Im doing something wrong but several did copy. I tried using Safari, after changing the preference to "Pulp" but the feed does not get added to Pulp.

I cant use this program.
