RSS Feeds are 404

Hi everyone! I setup and installed WP tonight and having a good time with it so far. However I cannot get the RSS feeds to work. The Files are there under my web folder however whenever you click the link to the feeds you get a 404 (NOTE: I have removed the feed:, doesn’t help), the current links are located at https://www.o2slim.com

Any help would be great thanks! ??
