I followed the instructions EXACTLY for upgrading from registered version 3 to registered version 4.  (First made sure all instances of Visual Basic .NET were closed, and then uninstalled from the Uninstall link on the Start Menu.  Then I installed version 4).
Unfortunately, when I open my projects, they had all lost all MySqlConnection and MySqlDataAdapter objects, thus creating multiple errors within my application (and I have MULTIPLE connections and dataadapters for different forms).  Thankfully, reinstalling version 3 and restoring my project from a backup resolved everything, but this problem is reproducible.
Perhaps some useful information for debugging - my MySqlConnection and MySqlDataAdapters are named OleDbConnection1 and OleDbDataAdapter1 since I used the Migration Wizard.  Perhaps that is where things get messed up when upgrading?
