More or less suddenly, a majority of the HTML modules on my local test installation began throwing this error:

DotNetNuke.Services.Exceptions.ModuleLoadException: The type initializer for 'DotNetNuke.Modules.Html.DataProvider' threw an exception. ---> System.TypeInitializationException: The type initializer for 'DotNetNuke.Modules.Html.DataProvider' threw an exception. ---> System.MissingMethodException: Method not found: 'System.Object DotNetNuke.Framework.Reflection.CreateObject(System.String, System.String, System.String, System.String, Boolean, Boolean)'....

Any ideas on what this could be would be greatly appreciated. I can always blow the installation away and restart, but would prefer to avoid that fate.

Thanks.
