There is a problem with OpenOffice 2.0 bundled with Asus EEE PC. This version is not capable to open some extensions, which are important. You might want to upgrade OpenOffice.org to work on those extensions.
This how-to describes the installation of Openoffice.org in an external device like a SD-card or a usb stick, without removing the original version of openoffice which comes in your eeepc. Or remove it anyway:)
