vb.net - Unrecognised database format exception -


i have connect programs database.
edit database in access, , after when running program, error notice unrecognised database format.

then try make new database , connect vb.net failed again.
don't know fault because didn't change in code.
use provider microsoft.ace.oledb.12.0 , file extension in .accdb format.

first possibility: database might have been corrupted. try compact , repair.

second possibility: inadvertently database format changed, if case can "save as" lower version 2003 or 2010.
