Still no luck. Anybody have any clues on this? I did a quick google search and saw that somebody on these forums posted this awhile back, but never got a resolution as he was trying to dual-box an account that wasn't his (against TOS).

I, however, own both these accounts and would love to get up and running dual-boxing. Since somebody else has had this problem before (and he said it worked on his laptop but not his desktop), it leads me to believe it's a configuration issue, but I'm stumped as to what the configuration issue could be. I've tried with my firewall off (for those who are going to jump to that conclusion), and it didn't help...
