Word Document Recovered

Hi :

I used Recuva to recover some Word docs this week.

While I seemed to have recovered them, I am unable to open some of them

The Recovered Word Docs that I am able to open are Word 2003

The ones I am not able to open are Word 2007

I run word XP / Word 2003 on my laptop

I have installed the Converter for quite some months now and hence I am able to open 'fresh' Word 2007 Docs

So is there anything I need to do to differently for the Recovered Word 2007 Docs?

Appreciate the help

Thanks

Sharath
