BusyContacts did not download any photos after adding a new account

There is a known issue with how temporary files on the mac are stored and managed. At times, after adding a new iCloud or Exchange account, especially via the Setup Wizard, you may notice that none or several of the photos associated with your contacts do not show you.

A simple, albeit inconvenient, solution to this problem is to open Preferences > Accounts in BusyContacts, and then removing and re-adding the affected account. This second retry seems to always work.
