No problem, it there for questions and reporting issues!
Unfortunately, the scene you mention is paid content, so I cannot test it on this one. The error you mention however does not sound like from my plugin, but it could be a VaM system error message due to something my plugin does.
Setting it up should be really simple now:
1. Ensure your animations are on 291 version timeline
2. Add the Camride plugin to your person atom
3. Open the plugins UI and select the person atom with the timeline animations
4. Click on "Add CamRide Layer to ..." in the plugin's UI on the left
Could you please send me a screenshot of how your atom list looks like after doing the above steps (click on the arrow symbol)?
Mine looks like this after successfully adding the CamRide plugin and setting it up. It should contain the SubScene and the /CamRide atom inside it (see red marks):

So I did exactly the steps on the demo video you posted including updating the timeline plugin to 291 but no matter how much I click the capture function and then move the player view for keyframing the scene I used doesn't move or play the 5 secs keyframe like your demo scene do.
