Thank you for the response. However as you will see from the original post I have already tried 2 different networks plus a 4G connection on a phone. I have tried on my home PC, I have tried on my work PC and I have tried on my phone. ALL of these give me basically the same response. I get told that google cant scan this file for virus and then I select download anyway and then I get told of a network issue. Now I am prepared to believe that rebooting my home router ( which I have tried ) might fix one of the routes but I think its highly unlikely that my Phone on 4G is somehow corrupted in the same way that my PC on a home network is.
Sorry the pic is small I seem to have transferred it as a small image but you will see the basic fault is that there is a network error downloading from google.
Is it possible for example that you have to use google drive rather than go in without login. Anyway whatever other suggestion would be welcome. failing that I have a JB7 with a very old database and no way to update it.
thanks
