I've just had the same problem after installing my robo 200 onto a new laptop. Whatever I installed, downloaded etc failed to allow me to cut but an email to brian at graphtec cured it. he told me to:

"Make sure the CraftROBO is plugged in and switched on and go to the start menu, right click on Computer and choose properties. Once the system info window appears, choose device manager from the top left corner.

Once you have Device manager open look down the list for a section marked 'other devices' and press the [>] next to it and you should see your Graphtec machine. Select the machine, right click and select 'update driver software'. When the Update driver window appears, choose ‘Search Automatically for updated driver software’ and Windows should associate the driver for you."

That fixed it for me so hope it also works for you.
