I cannot get any ratings to show on my Silvo.

Obtain an API key from OMDb.  Activate the key using the link emailed to you.  Change your scraper to Universal Movie Scraper using edit source.  In the settings menu for the scraper in the same edit source window, adjust the settings for the rating scrapes you desire.  Add your OMDb key there also.  Be sure to obtain movie name from tmdb and not imdb.  Also, do a little research for EVERY UMS setting before saving your adjustments even if you think you know what they will or will not do.  I highly suggest you copy your entire appdata/roaming/kodi folder before doing anything so if you make a mistake you can start over. 

After saving the adjustments for UMS, you will be asked if you want to refresh the entire library.  That's up to you.  If you don't, you have the option of refreshing every title one by one using the info window for each title.  That's what I opted for choosing NO for every refresh question.  As soon as the refresh completes, the rating icons appear.  Hope this gives you some insight.

I see my main problem.I am not using Library but a third party add-on with Trakt.tv so probably will not work.

UPDATE I am also trying out another skin with  a third party add-on and Trakt and all the ratings are displayed perfectly.
