If I press the Test button it says: Cannot establish connection to the remote server.
My internet connection works fine.
I am able to download data which had been downloaded before already. If i am creating a similar filestructure for AUDNZD as well, then I there is no error message upon downloading anymore. So it seems to be related to access rights.
I solved the problem. I am using norton internet security which uses its own firewall. So windows firewall is switched off while Norton is on. Some settings must have changed because if i switch norton off as well then everything works fine.
