Erro: My form did not open..What can Ido to fix this problem?

Dr Sr,

I was elaborating my form with inserting tables and relating with the dats from my Data model. When I tried to open this form the bug "Guid = 2ff6e1fd-fcb5-4d52-a464-a47c5e921704 not exist on valid tables (ATTIB, FACT, BASCOPEITEMDEF, ENTITY) for XPath elem" appeared.

The Details of error:

"System.Exception: Guid = 2ff6e1fd-fcb5-4d52-a464-a47c5e921704 not exist on valid tables (ATTIB, FACT, BASCOPEITEMDEF, ENTITY) for XPath elements

How can I solve this?

I want to fix what is wrong and keep doing my process.
