Perform the following checks:

Verify that your PC clock is correctly set.

Verify that you are using version 1963 of MSE (as of June 28 2010). For more information, review .

Remove Zone Alarm if you have it and use the Windows Firewall.

Verify that you are not using a proxy server.

Verify that you have “install updates automatically” selected in Windows Update (even though the MSE definition updates are optional).
