Since my Windows 10 Anniversary download I have been getting the error message" Product Activation error code 1-80004005." when opening the programme which is strange since the programme has been working perfectly since purchase in 2007. I am allowed 30 minutes of use and then it shuts down. I have the Activation code on the original box and discs but there is no way of inserting it into the programme as far as I can see. Can anyone advise me what to do please. So far I have had lengthy chats with Microsoft Support (Games) who are amazingly clueless as to what I can do. Thanks.
