Just trying to check on the obvious here, but have you tried running rake db:drop? Whenever I make changes to my migrations, I need to drop all of my DB tables before I try to create and migrate them.

So the full operation would be rake db:drop db:create db:migrate

Oh, and you can also try to specify the environment (I sometimes need to do that on test environments), e.g. rake RAILS_ENV=test db:drop db:create db:migrate
