I have a label format with a database in an excel file. I have a second database in another excel file. The two files have identical field names and data types. When I go to the Database Connection Wizard to switch to the second file I get the message "The format of the database in .... does not match the old database". 

How can I just switch files, or find out why it thinks the two files don't have the same format ?

Thanks in advance.
