my house was built in 1958, it is not grounded, we probably did not pay attention to the inspector when he did our house or he didn't mention it, anyway, our home is not grounded, we tried to get ATTUverse installed and the person said he couldn't because the house isn't grounded. He also said it could be dangerous living in a house that is not grounded, our outlets are only 2 prong. How can we fix the problem without spending too much money
