Try to just countinue everything and ignoring the fact there should be a Tibia.cfg.bak file.
You mean it will still work?
Edit: This doesnt work for me! If i go to my "Tibia - Druid" and change to exevo gran mas frigo. then i go to > "Tibia - Sorcerer" and change to flam". then go back to "Tibia Druid" its still Flam......
