Thanks again Alan, I hate to say this, but I have reinstalled and used my member password to to register it again. I'm going to try not to worry about the update and just use the programme when I need it and see if the auto update works. A busy server is all I can think of now.
I will let you know what happens after the next update.
Of course it could be Windows 10 assing around again. It is a new bought genuine install as the update was very poor. The rig 10 is on isn't that old, so 10 should work fine, but a few things are screwy with it on occasions. Windows 7 worked perfectly on it previously.
