I downloaded a file from the site below. It's the Wii L Data Viewer. Its the first file you see named Viewer Application. http://www.amaze-inc.com/CS526/proj3/ The problem is that the program gets a System.IO.FileNotFoundException error. I tried to debug it by reading the source code but i do not know C#. All i was able to figure out is that there is a vtkFormsWindow error when you view the forms.cs, i think. So, can anybody be helpful enough to identify the error so that i could make the program run? What file is missing which i need to download? Currently, forcing my self to learn c#. Any help would be greatly appreciated. Thank you.
