I cannot get autoblog work. It will post one item then it

I cannot get autoblog work. It will post one item then it won't add any more. I have it set up on 2 differnet sites on 2 different hosts and it doesn't work on either.
It processes the feed, but doesn't add it. If i try to process the feed again it says it has already been imported. I can see the title of the second item it says it imported but the "view post" link links to the first post!?
