A veces y por motivos que no comprendo, el juego simplemente no va. Cuando yo recién lo compré también tuve problemas para iniciarlo. Solía usar la versión ejecutable, pero me pasé a la instalable y me corrió bien. También puede haberse visto alterado por algún cambio en el perfil con el que juegas.

Saludos, espero y puedas solucionar tu problema.
