Problem restoring iWork from Time Machine

Hi all, just have a little problem I was hoping some one could help with.

For the record i'm running an up to date Lion and using a late 2009 MBP.

When I previously used Snow Leopard I ran iWork ('08) but then upgraded to Lion and got Office 2011. However, I would still like to use to use iWork. I use Time Machine so I went to a date when iWork was installed and copied the folder back to the Applications folder on my current Lion Setup, however when I try and run this it says some files are missing.

Does anyone know which files are missing and where I can find them within my Time Machine backup?

Thanks for the help. If you require any more info just ask.
