Redmine

We have a püroblem with migrating a plugin called "redmine-blocks".
We removed old folder in /redmine/vendor/plugins and created new one.
Then we called "rake db:migrate_plugins RAILS_ENV=production" in /redmine folder a no database migration took place.
We restarted apache and when clicking on project we get internal error and this log:

ctionView::TemplateError (Mysql::Error: Table 'redmine.overview_blocks' doesn't exist: SHOW FIELDS FROM `overview_blocks`) on line #88 of vendor/plugins/projects_tree_view/app/views/projects/show.rhtml:

As we take a look into mysql database "redmine", there is no table created with that name "overview_blocks".
Then we took a look into the plugins folder vendor/plugins/redmine_blocks/db/migrate and into the file "001_create_tables.rb"

class CreateTables < ActiveRecord::Migration
  def self.up
    create_table :overview_blocks do |t|
      t.column :project_id, :integer, :null =>false
      t.column :name, :string, :unique=>true, :null => false
    end

    create_table :home_blocks do |t|
      t.column :name, :string, :unique=>true, :null => false
    end

    Project.find(:all).each do |prj|
      OverviewBlock.new do |ob|
        ob.project_id = prj.id
        ob.name = 'members'
        ob.save
      end

      OverviewBlock.new do |ob|
        ob.project_id = prj.id
        ob.name = 'news'
        ob.save
      end

      OverviewBlock.new do |ob|
        ob.project_id = prj.id
        ob.name = 'issues'
        ob.save
      end
    end

  end

  def self.down
    drop_table :overview_blocks
    drop_table :home_blocks
  end
end

This look all right, but why does redmine migrate:db does not create this needed tables?
Is thete any reference table we have to clean up manually or do we have to rake "uinstall" something?

Tx for help
