Two weeks ago I bought a new laptop running windows 7, internet through TTnet, and have been unable to connect to the Google Earth server despite uninstalling and re-installing various versions and doing various bits of 'jiggery-pokery' (including changing DNS settings on laptop
and modem) after googling the problem.
I got peed off and gave up.
I am now in the UK for a few weeks, tried it and it worked first time!
I am sure that the government in Turkey have something to do with this and are making things difficult for Google because it owns YouTube.
