I just downloaded and installed version 1.3 of the framework. I’m able to run the sample application but when I try to associate table structures to the business objects using the Business Object Mapper window I get the following error message

“The fields could not be displayed. Verify that the project and/or business object configuration is setup properly.”

What was the error message that you received? If you got it in a message box, then it's not because you have a bad connection string. Also, try right-clicking the business object and tell it to build the partial class. When the progress window displays, it will give you an error message which is generally the message of an exception that might give us some more information.

Don't worry about getting me the error message, because Daniel had the same problem... it's been fixed and posted out on the Update Blog.
