The download adds the ability to Word to read Works files from within Word itself.
That is what I am thinking also. XP and Windows Vista on use different file locations for profiles. It is probably looking for something in the XP profile folder that doesn't exist in 8. You may look at the data source to see if you can figure out what it is looking for.I'm guessing that the table was imported from an external file which didn't go along for the ride when you moved the final document to your new computer. Therefore MS Word can't find the table's original file. Even if you do move the table file to the new computer, Word probably won't find it because the reference to it in the document file will point to the wrong location.
