Finally peace of mind, All ratings are updated,
the key is in these steps,

First of all remove simplecache.db (thanks to cscott1) , it's nessasary to build all ratings on widgets without conflicting previous Ratings otherwise it won't update on widgets whether you remove skin or reset, and if you remove simplecache.db after scrape then rating wont work.

Now use UMS with Rotten tomato Audience select as default, add all omdb,tmdb, fanart Api keys and scrape the library.

After that add same omdb, tmdb, fanart api keys in skin meta module of bingie.

Lastly generate new widgets without restoring earlier backups.
