Might need an alsignup and NoRegion Loader. NoRegion Loader should be all you need if, you have everything set to Japanese. (might have to keep opening it with the NoRegion Loader till a patched version or crack gets posted)
What may work for you.
NoRegion Loader.exe inside a No Region Loader.rar from a game(s) posted by girlcelly. Just move the NoRegion Loader.exe into the folder with the SiglusEngine.exe. (Frill Folder / 凛戒学園 Folder) Use the NoRegion Loader.exe, select the SiglusEngine.exe, click okay, save log...
