Well, now, which is it: The game goes to a white screen immediately after the last of the logos/movies (like you said in one post) or it goes all white when you enter the Temple of Trials (like you said in another post)? It makes a difference. This needs to be resolved first. I have no answer for you if it happens after the logos/movies.
It's a little different if it does this when you enter the Temple of Trials. There is an error usually resulting in an all black screen if you don't set the files inside the data/proto/critters folder and data/proto/items folder to read only. Check that. There are more than a few posts regarding black screens, proto files needing to be read only, and files from .rar archives.
