'This element cannot be found in the current page.' Pop-up

I'm working on a testing an older web site with Test Studio. There are parts of the page where the frame is recognized but not the elements within. I get a pop-up window that says "This element cannot be found in the current page. There's probably a problem parsing the page source, make sure the source is valid!" This is covered in the documentation. It basically says that the code is bad enough that Test Studio can't deal with it. Is there a way to get Test Studio to recognize the 'bad' elements?
