Guide Plus on RCA television

Question

We are unable to receive updates for the Guide Plus on our RCA model t.v. When we hit the Guide button (on remote) we get the following message. We are sorry that your television is not able to receive data to update your guide plus television listings. Likely reason is your cable company has blocked the information contained in the television signal. Please contact cable company and ask them not to interfere with the free data contained in over the air broadcast signal which supports your Guide Plus feature. I have contacted the cable company, and they advise they are not blocking any information. They advise to contact RCA for the solution.
