Installing OpenOffice 3.0 in Kubuntu Intrepid 8.10

I tried to use the PPA package:
deb intrepid main
However, OpenOffice 3.0 cannot open any file. I can start a new file, but cannot open file. So I remove them and tried the one from the website.

I downloaded the *deb.tar.gz file, then before installing it, I remove .openoffice* folder from my home directory.

Then unzip the *deb.tar.gz and go to the folder DEBS, cp the *.deb file for Debian from desktop-integration folder to the DEBS folder, then run this:

sudo dpkg -i *.deb
