Yea I've read a few websites about that error, too. But it seems to appear rather random and there isn't really a fix that works for everyone. Very unfortunate.
Let's try this if you're willing to: I've uploaded a version of the game that is not boxed by the Enigma program. So you have to scroll all the way down in the game folder to the RPG_RT.exe in order to play. Maybe you can avoid the error with that. [LINK EDITED OUT]
