What's causing iTunes to randomly display a 4002 error?
Once every day or two, iTunes seemingly randomly displays a 4002 error:
This is particularly puzzling to me, as the majority of the time (if not always) iTunes is in the background, and has been for a while. What exactly does the error signify, and how can I fix it?
Solution 1:
I got rid of this pesky error by
- turning iTunes Match off
- quit iTunes
- launch iTunes
- turn iTunes Match on
The first time iTunes complained with error 5002 during Match startup, but then it worked.
