RedmineもRubyも触り始めたばかりで対策がわからずに困っています。  
アドバイスお願いします。

[問題]  
Redmineにcontacts(CRM)プラグインを導入してメニューのコンタクトのページに行くと  
500エラーが発生する。

[環境]  
Win7 x64  
Bitnami Redmine 3.3.3-0  
[Redmine CRM plugin (Light
version)](http://www.redmine.org/plugins/redmine_contacts)

[実施したこと]  
プラグインをフォルダにコピー後に下記コマンドを実行

```

    bundle install --without development test RAILS_ENV=production
    bundle exec rake redmine:plugins NAME=redmine_contacts RAILS_ENV=production
    rake db:migrate RAILS_ENV="production"
    
```

サーバー再起動
