My first inclination is that you either missed something like a security/virus program (as you didn't mention adding an exception for the real time scanning), or you need to recycle your router, or there is another program causing issues like IE10 or Pando. Make sure you completely take all exceptions/ports out then add them back in the exact way they mention. Make sure the ranges are 9000-9013 UDP outbound and 2900-2913 UDP outbound and port 80 TCP.
If your ISP (or another program) has any of those blocked, eventually you will have problems.
