Denford Software & Machines

I am getting the above error when trying run a program using the virtual machine.

When does the error occur as soon as you press the VR Machine button?

Does the software connect and run your machine OK?

Has the VR option run OK before ?

What version of VR Milling are you using ?

"Catastrophic failure" is something to do with OpenGL 3D - check and update your graphic card drivers.
Confirm the problem by reducing hardware acceleration to None (see this post for details on how to do that: viewtopic.php?t=289)
