I have been exploring the changes to DotNetNuke 5 and noticed that the Map module does not work in 5.0. When you go to edit the settings the following error occurs.
Method not found: 'Void DotNetNuke.Services.Exceptions.Exceptions.Process
ModuleLoadException(System.String, DotNetNuke.Entities.Modules.PortalModuleBase, System.Exception, Boolean)'.
I downloaded the Map Module source and found that all that was needed was to recompile the module for DNN 5.0.0.
