I had the same problem. I think there might be something wrong with
the migrations.
If you manually set the lock_version on your database tables to 0
(zero) instead of NULL (which I assume is the problem) you should be ok.
I didn't see you're earlier email, otherwise I would have responded.
Does this work for you? I've been meaning to look at the code and
submit a patch if necessary but haven't had time.
