Process flows pulling up incorrectly after update

Situation:

All I see on the process flow is a green start event and red end event.  There is an error.  This is the message box that pops up:

and here is the details about the exception:

com.adeptia.indigo.transaction.IndigoTransaction; local class incompatible: stream classdesc serialVersionUID = 873405335548448526, local class serialVersionUID = -40496751949340404

java.io.ObjectInputStream.readOrdinaryObject(Unknown Source)....

 

We can run the flows, it appears.  However, when looking into the repository, this is the error received:

 

Here are the details:

Cause: The Adeptia services may have not been stopped completely before the upgrade was initiated.

 

Solution:

1) Stop the Adeptia Services
2) Identifying any running java services associated with Adeptia 

-  In Linux, you can use the command

ps aux | grep java

- In Windows, you can go to the Task Manager > Processes tab.

3) Killing those processes
4) Start the Adeptia Services
