Use my client, its easier. Its clean, so you dont need to worry about it. Not even playing RL tibia :/
Also if you want to use an OTclient or so.. you need tibia 10.90, and to copy the tibia.dat and spr from my client, to yours, and then use the ipchanger with the ip: tlkservers.ddns.net and port: 7171 (You can also try to use ip: tlkserve.ddns.net)
Also, using my client is easier, extract and play, no need for ipchanger nor anything else.
You can always reach me at our discord channel.
