Microsoft SQL Server Migration Assistant for Access Problem -- "There is nothing to process"

Hi. I am trying to migrate an MS Access 2003 database to MS SQL Server 2005, using the Microsoft SQL Server Migration Assistant for Access.

I have used the Migration Assistant successfully in the past.

Now, however, when I create a migration project, Add the database, connect to my MS SQL Server, and try to "Convert, Load, and Migrate" the MS Access 2003 database, I get an error:

"There is nothing to process."

The migration assistant will not convert, load, or migrate my database. Apparently the Assistant does not recognize or see the database?

A few months ago, jmoss111 very kindly helped me with this exact problem:

jmoss111 fixed the migration problem, but says that he had to "jump through hoops to do it including removing and creating indexes; copying, deleting, and renaming tables, and dropping sub datasheets".

Can someone tell me what I am doing wrong? Why does my Access 2003 database require all of these modifications before it will cooperate with the Microsoft SQL Server Migration Assistant for Access?

I do not see any subdatasheets in this database. There are six tables, unrelated. It's a very simple database. Six tables; each has data; but nothing complicated.

I'm really grateful for any help or ideas. I need to migrate this data ASAP.

Thanks so much.
