If the RPG_RT.exe has been renamed, then RPG Maker will not be able to locate it.
Rename it back to RPG_RT.exe (but not to
RPG_RT.exe.exe) and try loading it again.
If that's not the problem, then the game's been locked, in which case send me a PM (as I might still be able to help you)
That is really, really creepy.
What's creepy about collecting RPG Maker games?
I'M NOT THE ONLY ONE WHO COLLECTS THEM, YOU KNOW
