I'm new to DNN and am using 4.0.2.   I've installed the Events Module using the clean install from scratch.  When I try to create a page and install the events module into my any pane I'm getting the following message and the only way to get rid of this error is to delete the entire page and start from scratch.  Any guidance/assistance would be wonderful.

Unhandled error loading module.
DotNetNuke.Services.Exceptions.ModuleLoadException: Unhandled Error Adding Module to TopPane ---> System.Web.HttpException: Multiple controls with the same ID 'ctr386_DD' were found. FindControl requires that controls have unique IDs. at System.Web.UI.Control.FillNamedControlsTable(Control namingContainer, ControlCollection controls) at System.Web.UI.Control.FillNamedControlsTable(Control namingContainer, ControlCollection controls) at System.Web.UI.Control.EnsureNamedControlsTable() at System.Web.UI.Control.FindControl(String id, Int32 pathOffset) at System.Web.UI.Control.FindControl(String id) at DotNetNuke.Common.Globals.FindControlRecursive(Control objControl, String strControlName) at DotNetNuke.UI.Utilities.DNNClientAPI.EnableContainerDragAndDrop(Control objTitle, Control objContainer, Int32 ModuleID) at DotNetNuke.UI.Skins.Skin.InjectModule(Control objPane, ModuleInfo objModule, PortalSettings PortalSettings) --- End of inner exception stack trace ---

Thanks in advance.

Sherry,
I was finally able to resolve my problem when I deleted the module and reinstalled it fresh.  I also had to go into the database and do some data manipulation as well.  I think I had to manually change one of the tables I can't remember.
