A family of Microsoft relational database management systems designed for ease of use.
I would create new blank 2013 database, and then attempt to import all the objects. I suspect that a form or some object is damaged/corrupted. You quickly find out by importing all objects into a new database – if the import into the fresh database works, then you likely will be able to use the dependency checker.
And yes, the dependency checker is a fantastic built-in tool that few realize exists.
