I've had this running a while now. It appears to gather the correct data and report it correctly, but every so often, I get a database error. My forum serves 1000's of downloads a day, and this 'duplicate' error repeats itself on different downloads only once every couple of days.
Anyway, here's the error.

Database error in vBulletin 3.7.5:

Invalid SQL:

INSERT INTO attachmentviewslog (attachmentid, userid, dateline)
