Hi Lyn,
You might want to update to the 614 version available at microsoft.com.
What happens is that some spyware changes the LSP, and when it's repaired it
disables a critical piece of same.
Here's a fix, really so easy that I can use it:
Use the method below which fits your OS version. If you are on XP SP2, use
the second method:
1) (winsock reset for 2k, xp pre sp2, and 2003 pre sp1)

2) (Winsock reset for xpsp2)
netsh winsock reset
enter
restart machine.
After resetting Winsock, applications which have added themselves to the
stack will need to be reinstalled. These may include third-party VPN
clients, some McAfee privacy or network security related software, and
others--check what is working and what is not.
