Hi JiNXd. First off, please download this program (it's a freeware software) and check whether are your ports really forwarded correctly or not.
In case they're not, please contact your service provider for this.
All the best.
And yeah Saad I'll post a thread soon. However, if you're in hurry you can do it by yourself it's easy just like installing AMXX. You can PM me for help regarding this.
