You should try resetting winsock in that case.

1. Click start, type cmd in the Start Search box, right-click cmd.exe, click Run as administrator, and then press Continue.


2. Type netsh winsock reset at the command prompt, and then press ENTER.

Note If the command is typed incorrectly, you will receive an error message. Type the command again. When the command is completed successfully, a confirmation appears, followed by a new command prompt. Then, go to step 3.


3. Type exit, and then press ENTER. You should be prompted to reboot, if not you should reboot and test.

Resetting the TCP/IP stack might also help.
Right click the command prompt icon and run as admin type in the command below and hit enter.
netsh int ip reset c:\resetlog.log
