Trouble opening word documents

I have a MacBook Pro purchased in 2008 and my wife has an iMac purchased in 2007. We both have OSX 10.8.2 and Word 2011 14.2.4, with all updates applied. If she send herself a document from work where they use Word 2007. I can open any of those documents on my Pro, but she has trouble with documents tables in them, the content does not appear. The table is there, just no text within the tables. Other type of documents seem to open correctly, just nothing with tables. Does anyone have any idea why this might be? I can't find any difference in the Settings, so I'm at a loss. Please help.
