ERROR: System.ArgumentNullException: Value cannot be null. Parameter name: type at ...CreateInstance 
I have searched a lot and almost every person who has reported this error found it while installing the Gallery module and the solution was to remove a section of the .dnn file. However, this is not my case, so, unfortunately, these threads I found have been of little or no help.

Please bear with me and offer help if you can.

I am trying to create my own module in DNN 3.2.2 using the dnnJungle VS project templates. I open the DotNetNuke solution I downloaded from this site that has a total of 35 projects. Compile. Everything OK.

I then add a new project to the solution using the VB DNN Module template (I will eventually do this using C#, but I am using VB to avoid any compatibility problems while I figure this error out) and making sure I am saving it in a new folder under ...\DesktopModules. The template adds a bunch of folders and files to my project. However, I leave it untouched and simply add my new project to the BuildSupport project's references. Compile. Everything OK again.

I go to DNN, log on as host, go to Host|Module Definitions|Add New Module Definition and set the values as follows:

Module Name: CSPM01
Folder Name: CSPM01 (that's the name of the folder created under DesktopModules which contains my project)
Friendly Name: CSPM01
Description: {blank}
Version: {blank}
Controller Class: {blank}
Premium: {unchecked}

And hit "Update".

I then type "CSPM01" in the "New Definition" text box and hit "Add Definition". Then "Add Control" and set the following properties for my control:

Module: CSPM01
Definition: CSPM01
Key: {blank}
Title: {blank}
Source: DesktopModules/CSPM01/CSPM01.ascx
Type: View
View Order: {blank}
Icon: {Not Specified}
Help URL: {blank}

And hit "Update".

I then go to one of my pages and add my new module to the content pane and get the following error inside of the module frame:

Error: CSPM01 is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: The type initializer for "COMPANY.DNN.Modules.CSPM01.Data.DataProvider" threw an exception. ---} System.TypeInitializationException: The type initializer for "COMPANY.DNN.Modules.CSPM01.Data.DataProvider" threw an exception. ---} System.ArgumentNullException: Value cannot be null.

Please help.

Thank you in advance.

I need help with this too. These forums are not as helpful as the asp.net forums.

Do you have extra information under "Log Viewer" (Admin menu)?
