When trying to access the DAM when logged in as host, I get this error

Error: Digital Asset Management is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.DigitalAssets.Components.Controllers.DigitalAssetsController.GetFolderViewModel(IFolderInfo folder) at DotNetNuke.Modules.DigitalAssets.Components.Controllers.DigitalAssetsController.GetRootFolder(Int32 moduleId) at DotNetNuke.Modules.DigitalAssets.View.OnLoad(EventArgs e) --- End of inner exception stack trace ---

Thanks
