I have been able to get the program installed by downloading and running the exe. which indicated to me what you posted is correct. Thanks again. It appears to be a case of my ISP doing what we call in Australia "playing silly buggers".
Now it won't authorise my login. It says that my login is accepted in the settings panel but rejects it when I start the program. This cannot be related to my download problem so I will have to work on it. Ah, the wonders of modern technology
