Click Start > Programs > Accessories > right-click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the Command Prompt, type in the bold text, one command after the other, pressing Enter between each of them:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults: netsh int ipv6 reset reset.log

Reboot the computer.
