Microsoft.Xna.Framework apparently missing
I'm trying to run any of the simulations for robotics studio 1.5 with XP x64 edition, and I keep getting this error message:
System.TypeInitialisationException: The type initialiser for 'Dss.Transforms.TransformSimulationEngine.Transforms' threw an exception. > System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Xna.Framework, Version=1.0.0.0, Culture=neutral,PublicKeyToken=6d5c3888ef60e27d' or one of its dependencies. The system cannot find the file specified.
File name: 'Microsoft.Xna.Framework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6d5c3888ef60e27d' at Dss.Transforms.TransformSimulationEngine.Transforms.Register()
Can anybody help me with this problem?
I've tried reinstalling Xna to no avail, and I'm getting frustrated - I need this program to work for a University assignment.
