Problems with RSS Feed – 404 Not Found

My site has been working fine for a very long while, never had problems with RSS Feeds or anything like that. I currently use Feedburner to manage my feeds, so when people go to /feed/ it redirects to feedburner with my feeds. I’m running WP 2.1.

The problem is that just a couple of minutes ago something went wrong, I don’t have a clue, but every time I try to get into /feed/ it says that it’s not found. I’ve not changed anything in wordpress at all, and the only thing I was switching was hot-linking thing on my domain; I switched it back to off but I’m still having problems.

Please help T.T

By the way, I tried searching but the posts I found weren’t related to my specific issue (of how it happened and things like that).
