SOLVED!

After troubleshooting this problem for the last 24 hours, I noticed in the screencast that sambauers installed WordPress 2.7.0 and not 2.7.1 the most updated version to this date. So I did a fresh install with WP 2.7.0 and bbPress 1.06 Alpha exactly the way he said. AND IT WORKED ON THE FIRST TRY!
