Cannot open .project file

b I have a Turnkey installation of ES 801. It is running in a VM.
When I login to Workbench, the eclipse log records this exception (only the first few lines are listed, followed by the 'Caused by' line is listed below):
!ENTRY com.adobe.ide.singlesignon 4 4 2007-11-08 05:45:56.281
!MESSAGE login notification failed

java.lang.IllegalStateException

Caused by: org.eclipse.core.internal.resources.ResourceException: The project description file (.project) for es801-trnkey-a 87.128 is missing. This file contains important information about the project. The project will not function properly until this file is restored.

b I also get this message when I attempt to access the repository. This is when I am browsing for a Tempplate URL when a new xfaForm process variable is being specified. Again only the first few lines of trace and the 'Caused by' line are listed.
