Forgot to mention, when I reinstalled Office 2013 from the backup DVD, I didn't uninstall Office first. I put the DVD in the drive to just see what was on the disc and was going to uninstall before proceeding with a re-installation, But when I simply clicked on it to open the disc, it started the installation. So I just let it finish and it seemed to do the install fine with no error messages and it seems to be working fine. I wasn't sure what it was going to do without uninstalling Office first, but seemed to work out fine. The version on the DVD was pretty old version, so after it installed I just did an Office update which worked with not issues.
