Problems importing zip files for Process modeling tutorial

Im starting the Process Modeling Tutorial and ran into trouble right off the start. The tutorial requires 2 zip files he installed, see below. I successfully imported the 1st SQL file into the database environment as instructed by the tutorial; however the 2 zip files has failed. When I import the 2nd zip file into the Appian Designer environment only 2 out of 22 files correctly import and the Appian dialogue box tells me 20 problems occurred. Any ideas or advise to resolve this?

1. A database SQL script named: pm_tutorial_database_script.sql

2. The application installation package. Human Resources Example Application.zip
