I have incorrectly added an old version of CC_ImageHeader into a DNN 4.6 site. The module fails and says it can't find enough information to load, thus failing to show the admin menus for the module itself (so I can't delete it that way).  Is there some data I can delete from the tables or some other method by which I can remove the module from the pane in which it is inserted?

The actual error message is below.
Message: DotNetNuke.Services.Exceptions.ModuleLoadException: Error: CC_ImageHeader is currently unavailable. ---> System.InvalidCastException: Unable to cast object of type 'ASP.desktopmodules_cc_imageheader_viewcc_imageheader_ascx' to type 'DotNetNuke.Entities.Modules.PortalModuleBase'. at DotNetNuke.UI.Skins.Skin.InjectModule(Control objPane, ModuleInfo objModule, PortalSettings PortalSettings) --- End of inner exception stack trace --- at DotNetNuke.Services.Exceptions.Exceptions.ProcessModuleLoadException(String FriendlyMessage, PortalModuleBase ctrlModule, Exception exc, Boolean DisplayErrorMessage) at DotNetNuke.Services.Exceptions.Exceptions.ProcessModuleLoadException(PortalModuleBase ctrlModule, Exception exc) at DotNetNuke.UI.Skins.Skin.InjectModule(Control objPane, ModuleInfo objModule, PortalSettings PortalSettings)

If you can login as host, you can uninstall that module.  

If you can't login as host, but have access to the website directory, remove the module's directory from the DesktopModules directory.

If neither of these work, you'll have to dig into the database table.  If you have to do that, you may be able to figure out what you need to do from these tutorials:
If not, ask for more help.

I was afraid that uninstalling the module would make it impossible to remove the instance of the module from the pane (which was really what the error message looked like).

I found another trick that apparently takes advantage of a "feature" of DNN.  Install another module with a known control menu in the same pane.  That way, DNN forces differentiation between the 2 modules and re-instates a standard menu for the errant module (it was not the original CC_ImageHeader menu).  That menu had the "delete" option available, so I deleted both modules successfully from the pane.

Thanks for your help, and I'll file that suggestion too in case I screw this up again!
