log-in error

I am having an error while trying to log-in to one of my test projects. Note that, I haven’t created any new user ID or modified the Admin user.
Please see the message as attached.

The message states that there is no CHECK_TYPE table in the database. Try to generate update scripts and run them.

Thanks. I already had created tables in the database but don’t know why the’re deleted! Anyways, I have regenerated and now Ok.
