If that doesn't get it connected, try resetting the TCP stack
click the 'start' orb
type cmd in the search box
hold down Ctrl+Shift and hit Enter
(or right-click the result that appears at the top of the start menu, under Programs (1), and choose Run as administrator)
answer Yes to the UAC prompt
In the Administrator window that opens, run the command
netsh int ip reset c:\resetTCPlog.txt
When that finishes, close the Administrator window, reboot, then try your connection again.
If that didn't fix it, try also resetting Winsock2.
i.e. open an Administrator window as above, then run
netsh winsock reset
then close the Administrator window, reboot, and try your connection again.
