Collaboration API - project.store() error

Question

Hi,
I am attempting to create a collaboration project via the API using C#. I have based my code on the samples from the "Extending Server Functionality with Remote APIs: Collaboration Server" documentation.
The following code all works fine:
IPortletContext portletContext = PortletContextFactory.CreatePortletContext(System.Web.HttpContext.Current.Request, System.Web.HttpContext.Current.Response);
IPortletRequest portletRequest = portletContext.GetRequest();
stringloginToken = portletRequest.GetLoginToken();
Plumtree.Remote.PRC.IRemoteSession portalSession = portletContext.GetRemotePortalSession();
ICollaborationFactory collabFactory = portalSession.GetCollaborationFactory();
projectManager = collabFactory.GetProjectManager();
IProject project = projectManager.CreateProject("NewProjectName", "NewProjectDescription");
However, the next line fails:
project.store();
The exception raised is:
"System.Web.Services.Protocols.SoapException: Server was unable to process request. --> Invalid pointer at com.plumtree.remote.prc.soap.QueryInterfaceProcedures.QueryInterface(String sLoginToken, String sInterfaceID, String sUUID) in e:\latestbuild\Release\devkit\5.2.x\prc\src\dotnet\portalprocedures\QueryInterfaceProcedures.cs:line 63 at com.plumtree.remote.prc.xp.XPRemoteSession.getCollaborationRemoteServerFromGlobalMap(IXPQueryInterfaceProcedures queryInterfaceProcedures)"
I am using the following versions:
Collaboration Server 4.02
edk.dll 5.2.0
Portal Server 5.04
Is there anything I need to install on the Portal server to make the above versions/code compatible or is there a bug in the edk.dll?
Thanks in advance for any help.
Regards,
Greig

My first question would be you are on Collab 4.0.1+, correct?  Collab 4.0.0 does not have API support.
I would try hitting a URL in your browser that looks like this:  http://collabmachine:port/collab/services.  You should get a page back that says, "And now... Some Services" followed by a list of about 9 service names.
If you can get that, your API services are installed/registered.  But your installation probably has some kind of error.  So the next step would be to check your Collab logs for exceptions (located in /ptcollab/4.0/logs I think).
