So I been through all current StackOverFlow solutions for people reporting the unrecognized database error and none of them have been useful.
My only theory is that the database they are using is to complicated to be used as a data source for visual studio.Do you have any suggestions?
I may not tell you what the problem is but I solved this issue before by resaving the database file as Microsoft Access 2003. Goto Save Database As Access 2002-2003 (*.mdb) and then use the new file.
