Miguel asked if I have created a "server instance".  Yes I did.  It is local.  The error occurs when I click on the server instance and then click on OK (after first clicking on Server Administration, of course).

I realize this program is a Beta version.  I would have stuck with MySQL workbench 5.1, but it didn't appear to have any SQL editing capability.
