Okay, I've tried the offline installer this time and the title screen comes up. But that's as much as I can see. I can't click New Game or Continue. Option is the only button that works. Extra and Special gives me white screens but I can still hear the music.
Note that the offline installer only contains a 'bin' folder that they tell you to move into the root folder to replace the existing bin folder there. So the problem above (img link) is still occurring.
I got a reply from their support system saying that it sounds like a driver issue. So I go to update my driver but that is not the problem since it's already updated to the newest version. I have AMD Radeon HD 5700 Series. And then their other option was telling me to disable my graphic card and I'm like... "What? But that will screw with my computer -.-' " So I don't know what to do now :(
