Terrible news, the version of Cute Puzzle SP English for Dlsite no longer works, the store staff committed the mistake to replace the wrong version. It became worthless data (always online drm with PlayDRM as a plus), and the author decided no longer to sell the English works for Dlsite anymore. You can only purchase Whitecute games in English versions only on Steam, period.
Anyone that has a wrong version notify the store for their mistake.
Edit: It has been corrected after the merging process, all language versions are available
