Google earth cannot connect to server

Hi,
When I was at home doing some research work, I came to a point that I need some exact geographic coordinates of a certain area. My friend advised me to use Google Earth. So, I installed it in my computer, when I was about to use it an error appeared on my computer that tells me "We were unable to connect to the Google Earth servers to activate your account."
We were unable to connect to the Google Earth servers to activate your account.
For information about how to resolve this problem, would you like to run a diagnostic test? This test attempts to detect settings on your computer that might prevent Google Earth from functioning properly.
After I read the long error message, I immediately check my internet connection. All was up and running since I can browse the internet. I checked on my firewall and there was no restrictions. Please help me to find solution on my problem.
Thanks.
