The two tables are wp_slp_rep_query and wp_slp_rep_query_results.
Make sure reporting is checked. With the bad CSS formatting it is not always saving the checkbox for some reason. Click Pro Pack tab, check the box, click another tab, then back to Pro Pack tab and make sure it is still checked.
I have a patch coming shortly for Pro Pack 3.11.004 and SLP 3.11.19 that will address the admin UI on the Pro Pack and Reporting pages.
