Things I have tried:
Restarting the patcher(making sure in task manager its off before starting it again).
Restarting my computer.
Restarting my network(router, modem & Vonage phone).
Shutting down firewall(software and hardware) and antivirus.
I really have no idea why this happens and this isnt the first time I have had problems with Blizzard's patchers and it is quite frustrating.
