Xnews doesn't connect to newsgroups, stuck on "Getting new groups"?

Hi. I use Xnews to access the newsgroups (alt.binaries.sounds.mp3...etc) and I've never had any problems connecting until today. Usually, it just says "Getting new groups" and all the newsgroups show up immediately. Now, all of a sudden starting earlier today, it stays stuck on "Getting new groups"...and that's it. No matter what I try I can't access the newsgroups via Xnews now. It's not my Internet connection-my Internet still works fine on both of my computers and my iPod Touch. I use Shaw btw. Does anyone know anything about this? Can someone can help me out here? Thank you!
