umm where do you get the message? is it after you choose your character or before you even get to the character selection screen?
i get the message often on my desktop before i get to the character selection screen. if its the same problem as me then try closing down all other programs except latale. if that doesnt work you should also try running with vlow
if you are not using an old as dirt computer (like i am) then uh sry i cant help lol
