Beginner problems with FeedWordPress (how to start?)

Hello,

This question might be very basic but I’m new to WordPress. I have a website with a news-category. I want to aggregate the news from other sources. So I installed the FeedWordPress plugin. I added a source but it doesn’t find new posts. See here: https://dl.dropbox.com/u/1600561/available/synd1.png The feed address is correct.

Second problem: How can I implement the feeds into my news site? Do I have to select an option from this menu in WordPress admin area?: https://dl.dropbox.com/u/1600561/available/synd2.png My news site is blank at the moment.
