Hi
I'm sorry I haven't used the News package. But it looks like the object in your search queue is looking for a content_revision FTSContentProvider that doesn't exist in your system. The News package provides it's own FTSContentProvider news__datasource proc. Wait nevermind, all it does is call the content_revision datasource proc.
So you need to go to the ACS Service Contract page in your Site Map and load:
2257 FtsContentProvider, 927 content_revision [Uninstall]
That is what the News package is looking for.
Should work then, good luck:)
