Subscribe Me Problems

I’m using the 2 column layout, but I’ve tested with the other layouts as well. The problem is that when I click on the RSS Feed, I get “The page cannot be displayed” The weird part is that this feed was working fine. I didn’t change anything, to my knowledge. I checked the .htaccess file and updated the permalinks mods, just in case. Everything else seems to be working just fine. I’ve checked file permissions and have even re-uploaded all the files. I just can’t think of anything else. I appreciate any ideas for how to get this working again. HELP!
