Workbench Error 1005: Can't create table (errno: 150) durante la sincronizzazione

[pmi]

Ciao a tutti,
ho creato un modello con workbench, ma quando vado a sincronizzare con il database, ricevo il questo errore. Ho provato e riprovata ma proprio non capisco dove è l'errore. Qualcuno di voi riesce a capire dov'è il problema?
