For all with the same problem. Does Internet Explorer work for you? If IE doesn't work as well, look in Tools menu and make sure it isn't set to Work Offline. Assuming this isn't the problem. Some things to try.
As mentioned above, change the region location and see if they work now.
Start> Type inetcpl.cpl in search box and press enter> Click on the Connections tab> Click on LAN settings
Uncheck the Automatically detect settings box, and the other check boxes for proxy server and automatic configuration script, if they are slected
OK your way out and see if the problem is fixed
Start> Type UAC in search box and press enter
In UAC window, change the UAC level to see if this fixes the problem
If none of this works, post back and we'll see if we can think of something else.
