IT IS EITHER YOUR FIREWALL OR VIRUS PROTECTION PROGRAM BLOCKING WIN2DS!!! If you have already added the ports to windows firewall then it is your virus protection. I am using avast and I had the same "stuck on waiting problem". But you do not have to completely disable the virus protection. In avast all I did was go into firewall, then firewall settings and changed the setting "HOME/LOW RISK ZONE" to and it worked!! HOPE THIS HELPS!!
