hmmm. What version of the game are you using? Moenovel version or Jap version?
If you're using jap version ----> the current translation patch doesn't work for that version (download moenovel's instead and apply the patch to that one)
If you're using moenovel's version ------> likely a corrupt/incomplete patch install. Uninstall everything and remove patch files from install folder, then reinstall again and apply patch again
NOTE: Remember to be PATIENT while the patch applies itself (it takes 10 minutes or so to install. Leave it there, go make dinner, read, watch tv, go for a stroll... once you return it should be finished) and don't close the CMD window until you're PROMPTED: "press any key to continue"
NOTE 2: don't install the game in program files x86, make sure you install on C:
hope this helps, cheers :3
