Hey slmdtruk, your video isn't available yet, so I couldn't see what you were doing.
Can you please let us know what you mean by "it didn't work"? Are you starting a new campaign afterwards or loading a previous save? A previous save might be the culprit. If you've gone as far as starting from scratch with a fresh install, update and then fresh install of JSGME, following Silent Steel's directions exactly, then starting a new campaign, you should be ok.
And no, you're not stupid. At least not yet.
