tr;dr No valid string…make a ticket = tomoya, in most cases at least I think. Not sure though because I finished it a while ago. I'm sorry that doesn't really do much.
I'm on mac, i can't play the game and don't know what to do.
Also, the link that nightgalez gave in the comment are dead... Hope i will have an answer soon :)
I'm experiencing the black screen without the cursor working (i.e. I have a white cursor, no flower cursor).
I'm on windows 8 (64 bit).
I did all the other installation steps and could get the game running so long as I didn't try to get the English patch up.
I have switched over to Japanese Local, Location, and Format.
I restarted my computer.
I have installed the fix it patch by replacing all 4 of the files in the game folder.
It still doesn't work. I'll try repeating the steps later.
