Mubox Issue

Hi, I'm not fairly new to the concept of Multi-boxing and I've tried to make it work for a few days now. I see how this forum is mostly based on Multi-boxing for Wow but I was wondering if it's possible to Dual-box on a different MMO game. Now I've already given it a shot and ran into an issue.

I installed Mubox, configured it to what the tutorial said. And for some reason it won't let me run the Mubox server correctly. Is it because Mubox doesn't support the game I'm trying to Multi-box on? Or might it be that the default port (17520) isn't open? Will I need to port forward or will this just not happen on the game I'm playing (KalOnline).

~Thanks in advance

Not really sure on the software or game you are using.
Is there a Mubox homepage, with some kind of support?

I look at the FAQ, support section on their site. Nothing matches what I need help for it.

I don't know the Mubox software.
And I don't know the game you're trying either.

If there isn't much support for Mubox.
I'd suggest researching other boxing options, to see if they will run the game.
