Sure!
You must have changed the conditions for the automailer too in addition of upgrading which triggered a bug which was there before CBSubs 2.0.2 most probably.

, or turned joomla debug on which displayed that error message that was hidden before.
Looking at error message and understanding it: Your condition has status condition (in condition tab) of subscription as "Active" AND "Registered unpaid", leading to that error message (and if it would not bug, it wouldn't find any subscriptions to act upon). And the result when joomla debug is off and that error is not visible, is that it does what it should and doesn't find any subscriptions.
If you really need to send to all active and just subscribed without paying ones, please make 2 separate auto-mailers to work-around that bug.
That setting should be a drop-down single-select and not a multi-select:
