Export failing

Hi,

I'm trying to export a section of the tree in EPi7 (MVC).  At the end of the export I get the following error:

The following errors have occurred:
Exception: Content with Guid "2ff44c93-5ce2-4e5c-9cc9-69987c3a9344" was not found[]
Can't export package because: Content with Guid "2ff44c93-5ce2-4e5c-9cc9-69987c3a9344" was not found

I've checked the database (tblContent) and can't find the content with the GUID which makes sense since that is what the error is about.

The only way I can think of to get rid of this error is to find the broken link.  Any ideas how?

Thanks
