volg6576 For white screen specifically - when does it happen? If you see the Illusion logo and THEN you get white screen - more than likely the game is missing files it needs. For example, if you forget to check the AAUnlimited tab of the launcher to make sure it has PP2 option disabled and PPX enabled (or vice versa, but that should not be used - PP2 version is not being developed anymore; that is what JustAl meant by "F95 has an outdated copy").
On the other hand, if you get a white screen and never see the Illusion logo - the game does not even detect the main data file. And that would be...weird, to say the least, files going missing without you doing anything.
P.S. Which Windows version are you using, by the way? 10 or 11?
