I have been streaming The Roku APP on my firestick for 2 years now via Amazon's Silk Browser. I have a registered account with Roku but do not have a paid subscription. I have always bee able to stream free movies etc. A couple of months ago I went into the Roku App selected a movie for watching and got the error message DRM: Key System Access Denied! I received the same message on any feature I clicked on. The App has basically locked me out. What's up with that?
