When you try to create DB Diagram you may get following error:
Database diagram support objects cannot be installed because this database does not have a valid owner. To continue, first use the Files page of the Database Properties dialog box or the ALTER AUTHORIZATION statement to set the database owner to a valid login, then add the database diagram support objects.
To solve the problem do following:
1. Select properties of the database
2. Select page "Options" and in "Compatibility Level" select anything than change to "SQL Server 2005(90)"
3. Select page "Files" and enter "sa" as owner
