Saved search in finder not working

We just recently put a new hard drive in our imac. When I got it back, all of the saved searches I had in finder worked fine except one. When I click on that one nothing happens. I can move it to reorganize it, but it does nothing when I try to select it. I tried creating another saved search and when I go to click save, it does nothing. Really weird. Has anyone run into this before? I wish I could just delete it and start over, but it won't let me drag it to the trash.

One time I got it to come up with an error message. It said, something about an original document was missing.

Let me know what you think.
