Migrate is not working

[Girimana]

i have not been able to install the tool in my django app which is using postgreSQL. I was trying to migrate using "python manage.py migrate easyaudit " But I have an error which is saying : "raise AlreadyRegistered(msg)
django.contrib.admin.sites.AlreadyRegistered: The model CRUDEvent is already registered with 'easyaudit.AdminClass'." And if I go to the postgres in my database there is no such model inside.
Can I get some help please? Thanks a lot.
