I have a Powerbook early 2008 (4,1), it's been running snow leopard with two versions of Office available (X and 2008). After installing 2008 I noticed that the old Office documents (doc & xls) wouldn't open with the Office 2008, well they open but most of the content is missing. They still open fine with the Office X.
I have lived with this for some time because I have had the old version version of Office X available.
Today I upgraded the Mac to Lion..........oh dear, the old Office X no longer runs and so I am unable to open my old Office documents.
I also have a MacBook Pro (2009) running Lion and it also has Office 2008. I have transferred a couple of the problem documents from the other machine and they open just fine.
I am confused. Both machines have versions 12.2.9 of Word & Excel.
Any suggestions?
