fresh install gives Unknown Column error

I downloaded and enabled the module using drush, and set permissions (actually, the default permissions were perfect).

I then tried editing a view and adding "Content Lock: Is Locked " as a filter. (I set the option False, to filter out any locked content from my view.)

As soon as I added it, Views showed the following error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'content_lock.nid' in 'on clause'

With that filter in place, my view shows no results.

I tried replacing 3.0 Beta with 2.2, but I get the same error.

Any suggestions?

Thank you!
