Need auto blog help (can't add more)

We're having a problem with setting up the auto blog plugin.

We have it installed and all seemed to be working well until we tried to populate the plugin with some feeds.

Once we got to four, it stopped letting us create more. When we hit "add new", it begins to open the settings like all is well, but then the page automatically refreshes and we can't add more RSS feeds.

I know I've seen this happen to others but have not found any solutions. Any suggestions?
