This Analysis is incomplete...?

Win 7 (32), CCleaner 3.05.1408, PrivateFirewall (CCleaner Allowed/fast!), Avira Antivir Premium v10, and no other active anti-malware.

Every since I've upgraded to the latest version- The First time I click on Analyze, I get "This Analysis is incomplete" (see attachment)?

The Second time I re-click Analyze, it works OK?
