Your post is tagged with a Roku 1 model 2710. That is an older device, among the oldest and least powerful devices that Roku still supports. But, Roku still supports it.
However, as it is a less powerful device, occasionally, some apps stop working on it after those apps are updated. I do not know if that is the case with that screen saver and the 2710, but it is the case for some apps.
If the screen saver was updated and the update broke 2710 functionality, that may be permanent. However, it would be best if another user of that screen saver came by and reported any experience that is less than optimal.
