Unable to create project based on sample proposal.

Hi Folks,

I have a small issue where I cannot create a new project based on the default sample proposal project (using project server 2010).  Initially it was because there was no workflow but after removing and re-creating the 'Sample Proposal Workflow' I am getting a callback error  (callback.96|/wEWCAK......).  From memory this is because there is no project detail page associated.  

When I try and open the proposal project I am getting the error: "Unable to open project, no valid Project Detail Page could be found for the project'.

Does anyone have any information on how to reset (or create) the default project detail page(s) for the sample proposal site?    I am able to create basic sites just fine.

Regards

Andy
