Clearing dns cache -
Hold down the Windows Key and press X
Click Command Prompt (Admin).
When the command prompt opens, type ipconfig/flushdns and press enter.
Type ipconfig /registerdns and press Enter
Type ipconfig /release and press Enter.
Type ipconfig /renew and press Enter.
Type netsh winsock reset and press Enter.
Reboot your computer.
If this doesn't work, I would post under the other subforums.
