Let me help you memorize the report, Scabercrombie.
You don't have to turn on anything. You'll have to click the Memorize button in the report window to help you memorize it. From there, you can add the desired name and save it to a specific report group. You can also share the report template with others.
However, if it's a memorized report already and you made some changes, you'll receive a message if you want to save the modified report. Since it didn't ask on your end, it may be caused by a corrupted file. Let's run the Verify/Rebuild utility to detect the data damage.
