After Upgrade, lost my run configurations

I recently upgraded, and my python configurations no longer work.  How do I fix this?

I go "Edit Configurations" to see the Run/Debug Configurations dialog.  All my run configurations are showing as "unknown" with the error

**Run Configuration Error:** Broken configuration due to unavailable plugin or invalid configuration data.

The workspace.xml seems to still have the configs:

    <configuration name="Replicate Repo Local" type="PythonConfigurationType" factoryName="Python">
      <option name="INTERPRETER_OPTIONS" value="" />
      <option name="PARENT_ENVS" value="true" />
      <envs>
        <env name="PYTHONUNBUFFERED" value="1" />
      </envs>
      <option name="SDK_HOME" value="C:\Python27\python.exe" />
      <option name="WORKING_DIRECTORY" value="$PROJECT_DIR$" />
      <option name="IS_MODULE_SDK" value="false" />
      <option name="ADD_CONTENT_ROOTS" value="true" />
      <option name="ADD_SOURCE_ROOTS" value="true" />
      <module name="esReplicate" />
      <EXTENSION ID="PythonCoverageRunConfigurationExtension" enabled="false" sample_coverage="true" runner="coverage.py" />
      <option name="SCRIPT_NAME" value="replicate.py" />
      <option name="PARAMETERS" value="--settings=./resources/config/replicate_repo_local.json" />
      <option name="SHOW_COMMAND_LINE" value="false" />
      <option name="EMULATE_TERMINAL" value="false" />
      <option name="MODULE_MODE" value="false" />
    </configuration>
