I have created a custom module that has 3 user controls.  Each control inherits the PortalModuleBase Class.  Each user control uses the DotNetNuke.Modules.MyControl namespace.  My web application dll is in the bin of my website.  My user controls are in the DesktopModule's folder in a folder with the the module name.  Having said all of that I created a module definition with one of the user controls and I am able to put it on a page.  When I add the other 2 controls to the definition and try to put the module on the page it does nothing but when I look at the event viewer it states the below.  Any help is appreciated.  Thanks.

I figured it out. One of my user controls implemented the ModuleSettingsBase class. In my definition for that control in DNN I didn't have the control key set to "Settings". Once I used the proper key name it worked.
