Update 5.3 subs issue (Build 5015)

Hello Everyone, I am having some issues with my Roku 1. The subtitles used to work fine but not anymore. With the new update they implemented a new Captions feature in Settings, but I cannot see it. Its not there trust me. My build is 5015, most people are talking about other builds. I have all my family with Roku's so its not just mine (About 20-25 rokus linked to my account, all Roku 1's). I would like to change the Build of my Roku to one that does support this caption feature. It is very important to mention that I am not in the US... Is there such a thing to "Change a Rokus Build"?... All the Rokus are bought in the US, and are registered with an American Payment Method...

Any ideas would be greatly appreciated...

Thanks!
