I followed all your steps and indeed the error occured it happend after 10 sec's when the game runned, i can hide it, but my screen keeps white and unplayable.
using win vista 32.
If you are playing on a different server instead of rpg-club than the settings wont work for that server,
if you ARE playing on rpg-club than the settings wont work either cuz they have some anti-bot system, and ppl are trying to crack it.
