Corrupt Table In Word. File Not Usable.

I have Windows Vista on a laptop and Windows XP on my desk. Both systems have been used for a Word document I've been working on.This Word document has a contents table and one other freestanding table. One of them has become corrupt -- I do not know which one. I see a discussion string about this, but the solution proposed there does not work for me. When I open the document, I get the error message about the corrupt file, but the cursor doesn't work, page down doesn't work, the down arrow doesn't work, the links above doesn't work. The moment I click on the document to get a cursor, Word no longer responds (I get the not responding message up top), and then it just sits there. If I click again anywhere, the document goes gray, and all I can do is close it.
