I’ve had a problem forever that when iTunes closes, it forgets the password to the iTunes store, and it forgets the password to my Audible account. I’ve Googled it once or twice but couldn’t find the answer, and since I hardly ever close iTunes except for boots, and since Quicksilver is so fast to open 1Password to retrieve my passwords, it’s only been a minor annoyance. But today I wanted it fixed, and Audible has actually provided a few solutions. The last one worked for me, I moved the /Library/Preferences/com.audible.data.plist out of place, relaunched iTunes, entered the password, closed and reopened iTunes again, and it still works. Super! The new and old files differ not in size, but the key is different and the old file had some flags set on the file.
