DotNetNuke.Services.Exceptions.PageLoadException

On a fresh installation of DotNetNuke (Version 4.4.1) a customer recently reported the following error:

An error has occurred.
DotNetNuke.Services.Exceptions.PageLoadException: Value cannot be null. Parameter name: type ---> System.ArgumentNullException: Value cannot be null.

The error occured when the default blue vertical menu was selected.

Observing the install zip package and the other zip options it can be seen that a number of dlls are missing. These are listed below:

• DotNetNuke.ASP2MenuNavigationProvider.dll
• DotNetNuke.Caching.BroadcastPollingCachingProvider.dll
• DotNetNuke.Caching.BroadcastPollingCachingProvider.SQLDataProvider.dll
• DotNetNuke.DNNDropDownNavigationProvider.dll
• DotNetNuke.DNNMenuNavigationProvider.dll
• DotNetNuke.DNNTreeNavigationProvider.dll
