Post Cannot connect!
I am trying to set up the VEX cortex for my class and I am having trouble. This is the first time the cortex's have been linked to my laptops.
Currently, the cortex "Robot" light is blinking green and the "game" light is blinking very rapid green.
When I try to download firmware (master or robotc) it tells me no communication link is available.
I have tried all the techniques listed in the directions (holding config, restarting, etc) to no avail.

Have you installed the newest Cortex drivers?

What version of ROBOTC are you using? I recommend downloading the latest from: It includes all of the latest drivers.

Also it includes a "getting started" page that details the setup instructions. It will open automatically the first time ROBOTC is run, or by going to Help > Show Getting Started.
