document type disappeared (NOT deleted)

I am running Umbraco v4.0.2.1, ASP.NET 2.0 ,Windows Vista, IIS 6.0.

I just updated one of my templates and then went to look at the content node to edit the content to check the changes only to discover this error:

Server Error in '/' Application.

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I then looked at the document type for that page which also displays an error:

Server Error in '/' Application.

No node exists with id '1089'

I am sure I did NOT delete this document type. The document type still appears in the list even when the nodes are reloaded. The content nodes are also still showing. The page still displays after being republished and when looking at the source the changes to the template have been included. I made these exact changes to another template for a different document type and that has not been affected. This behaviour is not expected if the document type had been accidentally deleted, therefore I think it must be another problem.

Any ideas?

Ruth , I have similar problem - same error anyway. Using the Admin interface, all my nodes are missing below the top node. So , I have Content (with nothing below it), Developer (with nothing below it) etc.

umbraco v 4.0.2.1 (Assembly version: 1.0.3441.17657)

IIS7, SQL 2008
