Probably a very stupid question. When I enter my registration-code in Bookend it works fine. But I'm afraid Bookends does not remember it. Every time I start Bookend I have to enter the registration code again. How can I avoid this?
It's possible that there is a problem with Bookends preferences. Remove Bookends 9 AND Bookends 10 Preferences and relaunch Bookends. See if the serial number "takes" now...
Just an FYI in case anyone else in the future runs into the same issue: I had the same problem, searched here in the forum for "registration" and found the solution easily. I deleted the Bookends 9 preference (having already tried deleting the Bookends 10 prefs) and now the registration sticks. Hurrah!
