Stuck on "Connecting..."

I have a MacBook Pro, Mac OS X version 10.6.8
I don't know what the problem is, I've tried almost everything I can think of and find. I've tried every browser, reset cache, disabled firewalls, reset modems, made a 2nd account on my computer, and probably a couple other things. My sister's and dad's computers play it fine, my is the only one that can't seem to make it work. I login, click duel, and always get the same thing "Connecting..."

How about trying to log on with a different account?

A different DN account or different account on my computer? I've done it with a different account on my computer, and someone told me not to make another DN account since thats some sort of spam and could ban me or something.

I have the same problem, every time if I have tried to connect with my laptop to Dueling Network I got no connection and I don´t know why??
But with my smartphone I don´t have this problem

Well, I suggest that I redirect to the FAQ Section, your problem will be answered there.
And if you don't want to go there: Create a second on your computer and grant that account Admin Rights.
Worked every time for those who they tested it with.
