DataSet Visualizer Access is denied

I'm working on an ASP.NET project in Visual Studio 2010.

I opened the dataset visualizer for my dataset trying to view the datatable inside, but it's giving me an access denied error. I can view all other data visualizers without problem except for dataset.

the error message follows below:

************** Exception Text **************
System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

Please provide assistance, thank you
