i read through this is entire post and i see that your not being specific enough.
Like you say it doesn't work. What do you mean?
It crashes, it gives you disconnect sign, what?
Do you have basic things like an ipchanger, right version of tibia.
EXPLAIN WHAT YOU MEAN! GIVE Me any detail you think could be important. so i can diagnose the problem.
First off have you portforwarded? (if you don't know what that means type in to google and look it up)
If your port is not open or if you don't have ip changer these are all basic problems.
