Hi Graham, Delete your /tmp/* directory. Shutdown MySQL and Cassandra if you are not using persistence.
If you run with peristent=true, make sure to delete the seshat and playground DBs in both MySQL and Cassandra before next run. Try to run the system without your changes. When that is successful you can start your integration.
