Hey peeps, i know a lot of you keep having network or FTP problems so I'm here to help. I did this on my computer and now everything works. 
Sometimes Windows XP firewall breaks the connections between your computer and Martial Heroes game servers.
Check your Windows Firewall first and make sure your Windows Firewall allows Martial Heroes' ports to go through. You also can disable the firewall temporary just to make sure the problem is not with the firewall. Do not forget to turn it back on or else you can get hacked!!!!
You need to open ports below (All ports are TCP ports, not UDP)
(1) Autopatch : FTP, port number 21
(2) GameGuard Update : HTTP, port number 80
(3) Login server : 10000 and 10027 to 10040
(4) Game server : 13701 to 13799 , 13801 to 13899
Happy gaming
