can't play

[Unregistered]

I've played Harem heroes before but then deleted the game. now i've reinstalled it through nutakus installer (also tried via website). When i try to open the app it either does nothing at all or opens the game in some in game browser. It then says i should log in and install the game while i'm acctually playing the game.. when it somehow seems to work it ends up crashing in an internal server error.

I just want to play and get back the content i worked for earlier :/
