Code Generation Tools XML Processing Scripts Plug-in for CCS (CG_XML_CCS) not working in CCS5

I have been unable to get the CG_XML_CCS tools to work in CCS5. The situation is:

1. Installed Code Composer Studio Version: 5.1.0.09000 on Windows XP SP3. Targeting CC430 devices.
2. Installed cg_xml v2_30_00

3. Installed Cgxml Tools for CCS v1.0.0.9

4. In CCS5 use Project -> Import Existing CCS/CCE Eclipse Project and select "C:\Program Files\Texas Instruments\cg_xml_ccs\Cgxml_config" to import. The imported project doesn't appear in the Project Explorer view.
   
   The tooltip for the Cgxml Tools has appeared, but am not able to select any of the tools.
   
   
   The EclipseWS.log contains the following relating to the CG_XML_CCS tools
   !ENTRY org.eclipse.core.variables 4 120 2011-12-25 10:59:44.921

The CG_XML_CCS tools do work in Code Composer Studio Version: 4.1.3.00038 installed on the same PC.

Are the CG_XML_CCS tools supported under Code Composer Studio 5?
