Subscribers Plugin no longer working?

After some other plugin updates and then the SubscribersPlugin update. The plugin is no longer working. At the bottom the error states: " Failure on system requirement Common Plugin version 3.33.0 or later installed

Have you updated the Common Plugin?

Thank you @Dragonrider I have the latest (I believe) of the Common Plugin. Should I look to see if it need to be updated manually?

UPDATE:

Did as you suggested and it now updated and working. Thank you @Dragonrider
