You should have received a manual in the box you purchased but if you didn't, you didn't.
The onscreen Help button has everything that is in the manual. But it is harder to find the stuff. Click on the Help button. Click search. Enter Revent Library. Click on those words when they come up on the screen.
There it tells you how to check to see if you still have the Revent Library on your computer. I bet you find it is there. But if it got deleted, find, in the same spot, Help, Revent Library, how to reinstall it from your program CD.
Then, I suggest, you use that HELP button to read about Family Journal. Down near the bottom of that page it tells you how to include the Revent stuff in your journal.
