We will do our best to see to getting this added. However, in the mean time, the cable company not being listed will not affect your actual setup or use, just the extra guide provided by Zap2it. If you scroll to the bottom, you should see a "Not Listed" option, which will take you to the next step so you can setup the remote, which will give you access to the virtual remote, and with it your full guide as provided by your cable company.
I hope this helps!!!
