Recently installed plugin; didn't get daily digest.

Using this with bbPress plugin. Forum has been active for a couple months. Installed this plugin. I have 3 users subscribed. Someone posted in the forum yesterday. Daily Digest was set for 3am today. I should have gotten the Digest. Checked under 'Emails sent' and nothing is listed. I do receive the 'test email'. I do receive other emails from the site such as from wp-members, when someone requests membership.
