John, I have spent my weekend trying all the suggestions presented in your links. It has been quite frustrating. I always arrive at the serial number dialogue, for which I have no answers or a redemption code. There has to be a better way. This is wasting a tremendous amount of time going in circles. I really do no t know what next to do here. Lost the weekend use for work. What other options do you have?
