Connection ({0}) does not have a CARMA
subsystem established.
Explanation
The CARMA connection is no longer associated with
an RSE connection. The RSE connection could have been deleted or renamed.
User response
Recreate an RSE connection with the same name and
host, and try connecting to CARMA again. Alternatively, you can remove
the CARMA connection and create a new CARMA connection. Removing the
CARMA connection will remove the associations between CARMA and any
members extracted to remote and local projects.
